Description

Method and device for determining connection relationship between optical ports

technical field

The invention relates to the optical network technology, in particular to the determination technology of the connection relationship between the optical ports.

Background technique

The advancement of optical devices has greatly promoted the development of optical communication technology, especially the progress of erbium-doped fiber amplifier (EDFA, Erbium-Doped Fiber Amplifier) and optical multiplexing technology, which has promoted the development of wavelength division multiplexing (WDM, Wavelength Division Multiplex) The large-scale application of equipment, at present, the industry has been able to provide a Dense Wavelength Division Multiplex (DWDM, Dense Wavelength Division Multiplex) system in which a single optical fiber transmits up to 320 wavelength signals.

A WDM device is composed of many functional units with different functions. For example, a WDM device may include a wavelength-level optical signal processing unit. The wavelength-level optical signal processing unit is, for example, to add and drop the wavelength signal output by the wavelength conversion unit, etc. The operating optical multiplexer, optical demultiplexer or optical add-drop multiplexer can also be an optical channel protection unit for performing protection switching operations on wavelength signals; WDM equipment can also include an optical signal processing unit at the multiplex section level , such as an amplifier for amplifying the optical signal of the entire optical multiplexing section; the WDM device may also include a dispersion compensation unit for performing dispersion compensation on the main optical channel signal. In addition to the main optical channel signal processing unit, WDM can also include some auxiliary signal processing units, such as the line interface signal unit for multiplexing and demultiplexing the monitoring signal and the main optical channel signal, and the signal quality of the main optical channel An optical performance monitoring unit for monitoring, etc.

As we all know, there are not only a large number of optical fiber connections between WDM equipment and customer equipment, but also a large number of optical fiber connections between functional units in WDM equipment, wherein the optical fiber connections between equipment or between functional units in equipment are It is realized through the optical fiber connection between the optical ports of the equipment or functional unit. According to statistics, a considerable part of the faults on the existing optical network occur on the optical fiber connection. If the connection relationship between the optical ports is used to determine which optical fiber jumper is abnormal and other faults, it will be of great help to solve the problems existing in the operation and maintenance of the optical network. Questions are very helpful, so the question of how to determine the connection relationship between optical ports is imminent.

At present, those skilled in the art have proposed a method for automatic discovery of optical fiber connections, that is, a mechanical sensing device is embedded in the flange of each optical port in all functional units with optical ports of the optical network node. When an optical fiber jumper is inserted into the flange, the functional unit can detect that an optical fiber jumper is inserted into its own optical port through a mechanical sensing device, and then the functional unit will report the optical fiber jumper to the control unit or network management unit of the optical network node. The control unit or the network management unit records the fiber jumper insertion event of the functional unit, so as to discover the interconnection between the optical ports. In this method, by pre-configuring the optical port association rules of the control unit or network management unit, the mutual interconnection relationship between optical ports can be found, for example, under the one-to-one rule, two connected optical ports When the fiber jumper insertion event is reported, the two optical ports are considered to be connected. Under the one-to-many rule, the first optical port to report the fiber jumper insertion event is regarded as the main optical port in one-to-many. Afterwards, the optical port that reports the fiber jumper insertion event is considered as the slave optical port, so that it is determined that the master optical port and the slave optical port are interconnected.

After careful analysis and research, the inventor found that the above method can realize the automatic discovery of optical fiber connections, but this method has strict requirements for maintenance operators, that is, it is required to insert optical fiber jumpers in order to find the connection between the optical ports. However, in actual operation, the operation and maintenance personnel often perform unified operations on all the optical ports of a single board. If the optical ports are operated according to the connection relationship, there will be great differences with the existing operating habits. Moreover, when the optical fiber connection relationship between the optical ports has both one-to-one and one-to-many situations, the control unit or network management unit must constantly switch working modes, otherwise misjudgment may occur. Therefore, this method has the problem of inconvenient operation for both the maintenance operator and the control unit or network management unit of the optical network node, and it is difficult to be applied in practice.

Detailed ways

Below we will describe several embodiments of the present invention in detail with reference to the accompanying drawings.

First of all, it should be explained that the method and device of the present invention can be used to determine the connection relationship between the optical ports of the optical network node, and can also be used to determine the connection relationship between the optical ports of each functional unit in the optical network node , the two can be performed successively or simultaneously, wherein each functional unit in the optical network node can be an optical network device functional unit.

The first method for determining the connection relationship between optical ports provided by the present invention may include the following steps: loading an identifier on each optical outlet through which the optical wavelength signal or optical multiplex section signal passes, Detect the identification loaded on the optical wavelength signal or optical multiplex section signal on each optical entrance through which the optical wavelength signal or optical multiplex section signal passes; determine the distance between the optical entrance and the optical exit according to the result of the identification detection connection relationship.

Among them, the connection relationship between the light entrance and the light exit can be determined according to the following steps: according to the result of the identification detection, the number of the light exit signs detected by the light entrance is sorted from the least to the most; if there is a light entrance If the port only detects the mark of one light exit port, it is determined that there is a connection relationship between the light entry port and the light exit port corresponding to the mark.

Further, if it has been determined that there is a connection relationship between the light entrances that have detected n signs and the light exit port corresponding to a certain sign in the n signs, then it is determined that the light entrances that have detected n+1 signs and There is a connection relationship between the light exit ports corresponding to the detected different marks, wherein, among the n+1 marks, there are n marks and the n marks detected by the light entrance port where the n marks are detected It is exactly the same, n is an integer greater than 0; by analogy, the connection relationship between other light entrances and other light exits can be determined.

The first method provided by the present invention will be described in detail below with reference to FIG. 1 . As shown in Figure 1, it includes the following steps:

Step S101: Each light entrance determines the upstream light exit that may have a connection relationship with it.

There are many ways for the light entrance to detect the light exit that may have a connection relationship with it, and examples are given below.

On each optical outlet, the optical wavelength signal or the optical multiplexing section signal can be loaded with an identifier. The loading method can be simultaneous or time-sharing loading. The identifier can correspond to the optical outlet one by one, and the frequency, spreading code, The ID information carried by the identifier or the time slot information corresponding to the identifier may also be in one-to-one correspondence with the optical outlets.

After the optical wavelength signal or the optical multiplex section signal passes through multiple optical outlets, it will carry multiple different identifiers. When an optical wavelength signal or an optical multiplex section signal carrying multiple different identifiers arrives at a certain optical entrance, the optical entrance will perform optical detection on the optical wavelength signal or optical multiplex section signal, and demultiplex all the identifiers. If the result is greater than the system judgment threshold, the optical outlet that may be connected to this optical inlet can be determined. It should be noted that since an optical wavelength signal or an optical multiplex section signal can pass through multiple optical outlets and then arrive at a certain optical inlet, and each passing optical outlet can load a different identifier to the same optical wavelength signal or The optical multiplex section signal, therefore, the optical input port that receives the optical wavelength signal or the optical multiplex section signal can detect multiple optical output ports, but not every optical output port has a connection relationship with the optical input port. Theoretically, each light entrance can detect all light exits upstream of it, but if there is a wavelength-selective functional unit between the upstream light exit and the light entrance, the light entrance will not The upstream optical outlet may not be detected, for example, if the upstream amplifier is connected to another amplifier after passing through a wavelength selective crossover (WSS, Wavelength Select Switch), and the WSS selects the wavelength signal transmitted between the two amplifiers If there is a permanent switching, the downstream amplifier may not be able to detect the light outlet of the upstream amplifier. However, because the optical fiber itself is not sensitive to wavelength, between the light output port and the light input port at both ends of a fiber jumper, the light input port can definitely detect the corresponding light output port. Therefore, the above restrictions do not affect the optical port connection. relationship judgments.

Step S102: Summarize the corresponding relationship between each light entrance and the detected light exit that may have a connection relationship with it.

After each optical input port determines the optical output port that may have a connection relationship with it, it can report the optical output port that has a connection relationship with it. Of course, the optical network system can also actively query each optical input port for the optical output port that has a connection relationship with it. In addition, after summarizing the correspondences, the correspondences may also be sorted according to the number of light exits detected by each light entrance, for example, in descending order.

Step S103: Select a correspondence relationship in which one light entrance only corresponds to one light exit.

Generally speaking, if a light input port corresponds to only one light output port, it can be explained that this light input port has a connection relationship with this light output port. First determine the connection relationship between one light entrance and one light exit, so as to exclude some light entrances and light exits for the subsequent determination of the connection relationship.

In addition, after summarizing the correspondences, there may be multiple correspondences in which one light entrance only corresponds to one light exit. At this time, when selecting a correspondence between one light entrance and only one light One-to-one correspondence between the light outlets. Of course, one-to-one correspondence can also be selected according to certain conditions. small order etc.

Step S104: Delete the light outlet from other correspondences with the light outlet.

If there is this light exit in other correspondences, that is, other light entrances correspond to this light exit, it can be determined that although this light exit is the upstream light exit of these light entrances, it is not connected to these light entrances The light outlets should be connected to some other light outlets in the corresponding relationship. Therefore, if the connection relationship between a light outlet and a light inlet is determined, this light outlet can be connected to other light outlets. Delete the corresponding relationship of the light outlet.

Step S105: Judging whether there is still a corresponding relationship between one light entrance and only one light exit, if yes, return to step S104, otherwise go to step S106.

Step S106: Determine whether there is a light entrance that does not correspond to any light exit, if yes, go to step S107, otherwise end.

Step S107: Determine that the light entrance is not connected to any light exit.

It should be noted that, in step S101, if a light entrance does not determine that any light exit may have a connection relationship with it, the following situations can be determined according to the type of the light entrance: In the first case, if the light entrance is the optical entrance of an optical network node and needs to determine the optical exit of other optical network nodes that may have a connection relationship with it, then it can be determined that this optical entrance does not have a connection relationship with any optical network node’s optical exit; in the second case, If the optical entrance is the optical entrance of a certain functional unit in the optical network node and it is necessary to determine the optical exit of other functional units that may have a connection relationship with it, it can be determined that this optical entrance does not have any connection with the optical exit of any functional unit connection relationship. Similarly, if an optical outlet is not detected by any optical inlet, the following conditions can be determined according to the type of the optical outlet: In the first case, if the optical outlet is the optical outlet of an optical network node and it needs to be determined that it may have In the second case, if the optical outlet is a functional unit in the optical network node If it is necessary to determine the light entrance of other functional units that may have a connection relationship with it, it can be determined that the light exit does not have a connection relationship with the light entrance of any functional unit. In addition, if a certain light entrance does not determine that any light exit may have a connection relationship with it, or a certain light exit is not detected by any light entrance, it may also indicate that the optical fiber connected to this light entrance or light exit The jumper is faulty.

It should also be noted that in step S101, the optical wavelength signal or the optical multiplex section signal can be loaded on each optical output port at the same time. If the existence of the logo is detected, it can be determined that the light outlet corresponding to the logo is upstream of it. However, it is considered that the label may interfere with the optical wavelength signal or the optical multiplex section signal, and if multiple labels are loaded on the optical wavelength signal or the optical multiplex section signal at the same time, there will be a large impact on the optical wavelength signal or the optical multiplex section signal. Interference, therefore, if the optical wavelength signal or the optical multiplex section signal is time-division loaded with the label, it can avoid excessive interference to the optical wavelength signal or the optical multiplex section signal when determining the connection relationship of the optical port, resulting in bit errors.

In addition, step S106 and step S107 may be performed after steps S101, S102 and S104.

In order to facilitate those skilled in the art to understand the flow shown in FIG. 1 more clearly, two practical examples are listed below, and then the flow shown in FIG. 1 is described.

The first application embodiment is used to determine the connection relationship between the optical ports of the functional units of the optical network equipment. Suppose an optical network node includes functional unit A, functional unit B, functional unit C and functional unit D, and each functional unit includes optical input port 1, optical input port 2, optical input port 3, optical output port 1, and optical output port 2 And light outlet 3, of course, the number of light inlets of each functional unit may be different from the number of light outlets, and the number of light inlets or light outlets of each functional unit may also be different. For the convenience of description, it is assumed that the number is same.

After each light input port detects the light output port that may have a connection relationship with it, the corresponding relationship between each light input port and the light output port that may have a connection relationship with it is summarized as follows:

Table 1

It can be seen from Table 1 that the light entrances of functional units A and D and the light entrance 3 of functional unit B do not detect any light exit of any functional unit, which can explain that the light entrances of functional units A and D and the functional unit The light entrance 3 of B is not connected to any light exit of any functional unit.

After constructing Table 1, first select the correspondence between the light entrance 1 of functional unit B and the light exit 1 of functional unit A. Since this is a one-to-one correspondence, the light entrance 1 of functional unit B and the light exit 1 of functional unit A can be determined. The light outlet 1 of the functional unit A has a connection relationship.

The light outlet 1 of the functional unit A is deleted from other correspondences with the light outlet 1 of the functional unit A. In Table 1, the light outlet 1 of the functional unit A does not appear in other correspondences.

Then select the corresponding relationship between the light entrance 2 of functional unit B and the light exit 2 of functional unit A. Since this is a one-to-one correspondence, it can be determined that the light entrance 2 of functional unit B and the light exit of functional unit A Port 2 has a connection relationship.

Delete the light outlet 2 of functional unit A from the corresponding relationship of other light outlets 2 with functional unit A. In Table 1, only the light entrance 1 of functional unit C corresponds to the light outlet 2 of functional unit A, so set The light exit port 2 of the functional unit A is deleted from the set of light exit ports corresponding to the light entry port 1 of the functional unit C.

Then select the corresponding relationship between the light entrance 1 of the functional unit C and the light exit 3 of the functional unit B. Since this is a one-to-one correspondence, the light entrance 1 of the functional unit C and the light exit of the functional unit B can be determined. Port 3 has a connection relationship.

The light outlet 3 of the functional unit C is deleted from other correspondences with the light outlet 3 of the functional unit C. In Table 1, the light outlet 3 of the functional unit C does not appear in other correspondences.

Then select the corresponding relationship between the light entrance 3 of the functional unit C and the light exit 2 of the functional unit D. Since this is a one-to-one correspondence, the light entrance 3 of the functional unit C and the light exit of the functional unit D can be determined. Port 2 has a connection relationship.

Delete the light outlet 2 of functional unit D from the corresponding relationship of other light outlets 2 with functional unit D. In Table 1, only the light entrance 2 of functional unit C corresponds to the light outlet 2 of functional unit D, so the function The light outlet 2 of unit D is deleted from the set of light outlets corresponding to the light inlet 2 of functional unit C.

Finally, there is only one corresponding relationship between the light entrance 2 of the functional unit C and the light exit 1 of the functional unit B, so it can be determined that the light entrance 2 of the functional unit C has a connection relationship with the light exit 1 of the functional unit B.

So far, the connection relationship among the optical ports of functional unit A, functional unit B, functional unit C and functional unit D has been determined.

The second application embodiment is used to determine the connection relationship between the optical ports of the optical network nodes. Assuming that there are optical network node A, optical network node B, optical network node C and optical network node D in the optical network or a part of the optical network, each optical network node includes optical entrance 1, optical entrance 2, optical entrance 3. Optical outlet 1, optical outlet 2, and optical outlet 3. Of course, the number of optical inlets of each optical network node can be different from the number of optical outlets. The number of optical inlets or optical outlets of each optical network node can also be are not the same, here for the convenience of description, it is assumed that the numbers are the same.

After each light input port detects the light output port that may have a connection relationship with it, the corresponding relationship between each light input port and the light output port that may have a connection relationship with it is summarized as follows:

Table 2

It can be seen from Table 2 that the optical entrances of optical network nodes A and D and the optical entrance 3 of optical network node B have not detected any optical exit ports of any optical network node, which can explain that the optical entrances of optical network nodes A and D The optical port and the optical input port 3 of the optical network node B are not connected to any optical output port of any optical network node.

Other steps for determining the connection relationship between the optical ports of the optical network nodes are the same as those described in Table 1.

It should be noted that the process shown in FIG. 1 is only an embodiment of the first method of the present invention, and in practical applications, the first method of the present invention can also have many embodiments.

For example, according to the logo detection results, sort by the number of the light outlet logos detected by the light inlet; compare the logos detected by the two light inlets whose number of logo detections is greater than 1 and whose number difference is 1, if the two If there is only one difference between the detected marks of each light entrance, then there is a connection relationship between the light entrance with a larger number of mark detections and the light exit corresponding to the different marks; If the light entrance is used, it is determined that there is a connection relationship between the light entrance and the light exit corresponding to the identification. The essence of this method is to randomly find two light entrances that are sorted adjacent to each other, and the two light entrances have only one difference in the detected marks, then the light entrance with a large number of mark detections can be determined There is a connection relationship between the light outlets corresponding to the different identifiers. This method can be used for all the light entrances in the sequence, until the light exit ports that have a connection relationship with them are found for all the light entrances in the sequence.

For another example, according to the identification detection results, it can be sorted by the number of light exit port signs detected by the light entrance port; first find the light entrance port with the largest number of light exit port marks detected, and for the convenience of description, this light entry port is called the light entrance port A, and then find the light entrance whose number of detected light exit marks is one less than the number of light exit marks detected by light entrance A. Here, this light entrance is called light entrance B, where light entrance A and light entrance If the optical port B detects that there is one and only one different identifier, it can be determined that there is a connection relationship between the optical inlet A and the optical outlet corresponding to the different identifier. Then find the light entrance that has one fewer light exit marks than the light entrance B detected. Here, this light entrance is called light entrance C. Also use the method of comparing light entrance A and light entrance B to Comparing the light entrance B with the light entrance C, and so on, the connections between all the light entrances and the light exits can be determined. The essence of this method is to find the light exit port that has a connection relationship with each light entry port in the sequence in descending order of the number of detected light exit port identifiers. This approach is just the opposite of the approach shown in Figure 1.

The first method of the present invention can be implemented by various forms of devices, one of which can include: an identification loading unit, used to record the optical wavelength on each optical outlet through which the optical wavelength signal or the optical multiplex section signal passes. The signal or the optical multiplex section signal is loaded with an identification; the identification detection unit is used to detect the identification loaded by the optical wavelength signal or the optical multiplex section signal on each optical entrance through which the optical wavelength signal or the optical multiplex section signal passes; The connection relationship determination unit is configured to determine the connection relationship between the light entrance and the light exit according to the result of the identification detection.

In the WDM system, the fiber jumper connections between the optical ports are basically one-to-one, and the power loss during the process of the optical signal from the optical output port to the optical input port that is connected to this optical port is generally lower than 0.2 dB, and if the optical wavelength signal or optical multiplexing section signal does not pass through the amplifier, the power of the optical wavelength signal or optical multiplexing section signal should decrease gradually during the transmission process, so the optical wavelength signal or optical multiplexing section signal passing through a certain optical outlet When the signal of the optical segment passes through one or some subsequent optical entrances, the power of the optical wavelength signal or the optical multiplexing section signal when passing through this optical exit must be greater than the power when passing through these optical entrances, and the optical wavelength signal or optical multiplexing section The power of the signal passing through the light entrance connected to the light exit must be closer to the power of the light exit than the power of other subsequent light entrances. Therefore, the connection relationship between optical ports can also be determined by using the characteristics of power attenuation of optical wavelength signals or optical multiplex section signals during transmission.

Based on the above reasons, the present invention also provides a second method for determining the connection relationship between optical ports. The second method can be applied in the optical regeneration section. The optical regeneration section can refer to the distance traveled by the optical wavelength signal or the optical multiplexing section signal after regeneration or amplification and before the next regeneration or amplification, wherein the source of the optical regeneration section can be Amplifiers and other devices. The overall technical solution of the second method is: add an identifier to the emitted optical wavelength signal or optical multiplex section signal at the optical signal source, or add an identifier to the amplified optical wavelength signal or optical multiplex section signal on the optical regeneration section source , and detect the mark on each optical entrance and light exit in the optical regeneration section that the optical wavelength signal or the optical multiplex section signal passes through subsequently; determine the identity matching and power matching relationship between the light entrance and the light exit Describe the connection relationship between the light exit port and the light entry port.

Wherein, the connection relationship between the optical inlet and the optical outlet is determined according to the following steps: according to the power of the optical wavelength signal detected by the optical inlet, the power of the optical multiplex section signal or the power of the identification, the Sorting the optical entrances; adding the optical exits to the sequence of optical entrances according to the power of the optical wavelength signal detected on the optical exit, the power of the optical multiplex section signal or the power of the logo; if the If there is one and only one light outlet between two adjacent light inlets, it is determined that there is a connection relationship between the light outlet and the light inlet that detects a lower power among the two light inlets; if the light inlet If the light port has one and only one light exit port before the light entrance port, it is determined that there is a connection relationship between the light exit port and the light entrance port.

In addition, the connection relationship between the optical inlet port and the optical outlet port can also be determined according to the following steps: according to the power of the optical wavelength signal detected by the optical outlet port, the power of the optical multiplex section signal or the power of the identification, Sorting the optical outlets; adding the optical inlets to the sequence of optical outlets according to the power of the optical wavelength signal detected on the optical inlet, the power of the optical multiplex section signal, or the power of the logo; if the If there is one and only one light entrance between the two adjacent light exits, it is determined that there is a connection relationship between the light entrance and the light exit with higher power detected in the two light exits; if the light exit If there is one and only one light entrance behind the light exit, then it is determined that there is a connection relationship between the light exit and the light entrance.

Further, if the power of the optical wavelength signal detected on an optical entrance, the power of the optical multiplex section signal or the power of the sign is higher than the power of the optical wavelength signal detected on any optical exit, the power of the optical multiplex section signal or the power of the logo, it is determined that there is a connection relationship between the light inlet port and the light outlet port corresponding to the logo loaded by the optical signal source or the optical regeneration section source.

Further, if the power of the optical wavelength signal, the power of the optical multiplex section signal or the power of the logo detected on an optical outlet is different from the power of the optical wavelength signal detected on any optical entrance, the power of the optical multiplex section signal or If the marked power differences are greater than the preset power difference threshold, it is determined that the optical fiber connection relationship related to the optical outlet is abnormal.

The second method of the present invention will be described in detail below with reference to FIG. 2 . As shown in Figure 2, it includes the following steps:

Step S201: Adding an identifier to the emitted optical wavelength signal or optical multiplex section signal at the optical signal source, or loading an identifier to the amplified optical wavelength signal or optical multiplex section signal at the optical regeneration section source.

In the second method, only the optical signal source or the optical regeneration section source loads the logo in the emitted or amplified optical wavelength signal or optical multiplex section signal, while other optical outlets are the same as the optical entrance, only detect the logo, and do not load the logo . The optical signal source may be an optical network node, or a functional unit of an optical network device, such as a wavelength conversion unit.

Step S202: Detecting a mark on each optical input port and optical output port in the optical regeneration section through which the optical wavelength signal or the optical multiplex section signal passes.

Step S203: Summarize the corresponding relationships between the light entrances and light exits with the same number and contents of the detected signs and the detected information respectively into one group.

For an optical entrance or optical exit, if the optical wavelength signal or optical multiplexing section signal passing through this optical entrance or optical exit also passes through some other or some other optical entrances or exits, then this optical entrance or The number and content of the identifiers detected by the optical outlet will be exactly the same as those detected by one or some other optical inlets; if the optical wavelength signal or optical multiplex section signal passing through this optical inlet or optical outlet Do not pass through one or some other optical inlets or outlets, or if the optical wavelength signal or optical multiplex section signal that passes through one or some other optical inlets or outlets does not pass through this optical inlet or outlet, Then the quantity and content of the marks detected by this light entrance or light exit will be different from the quantity and content of the marks detected by one or some other light entrances.

In step S203, the corresponding relationship between the optical entrances that detect the same number and contents of the identifiers and all the detected identifiers and the corresponding optical power information can be summarized, and correspondingly, the random detection of the same number and contents Summarize the corresponding relationship between the optical exit port of the road identification signal and all the detected identifications and the corresponding optical power information, so that multiple optical input port groups and optical output port groups can be obtained, and the optical port detected by each group The number and content of the marks are exactly the same as those detected by other optical ports in the same group.

Step S204: Perform power matching on the optical ports of the same group, and the optical output port with the most power matching has a connection relationship with the optical input port.

Specifically, for the light exit or light entrance in each group, in the light entrance group or light exit group that detects the same number and content of the logo, find the most matching optical power corresponding to the detected logo The light entrance or light exit, the light entrance or light exit that is found is the light entrance or light exit that has a connection relationship with it.

If the optical entrances connected with the light exits are determined based on the light exits, the light exits in the light exit group can be sorted first, for example, sorted according to the order of power from large to small. Similarly, the corresponding The light entrances in the light entrance group are sorted, and the corresponding light entrance group refers to a group composed of all light entrances that have detected the same number and content of identifications as the light exits in the light exit group. After the sorting is completed, use the first light outlet in the light outlet group as a reference to determine the light entrance that has a connection relationship with the first light exit, that is, find the corresponding detected light from the corresponding light entrance group. The light input port whose power is less than and closest to the corresponding optical power detected by the first light output port. Generally speaking, the difference between the power of an optical wavelength signal or an optical multiplex section signal when it passes through a certain optical outlet and the power when it passes through an optical inlet that is connected to this optical outlet should be less than 0.2dB, but considering factors such as detection accuracy , it can be considered that the optical power difference can be less than 1dB. Therefore, the optical input port found should be the optical input port whose detected optical power is less than the optical power detected by the optical output port, and the difference should be less than 1dB. It is the light entrance that is connected to the first light exit. In the same way, use other light outlets as a benchmark to determine the light entrances that are connected to these light outlets. The light outlets in the light outlet group have connected light inlets, so that the connection relationship between the light ports can be determined.

In the same way, if the light-entrance port is used as the reference to determine the light-entry port that has a connection relationship with it, you can first sort the light-entry ports in the light-entry port group, for example, sort them in order of power from small to large. Similarly, The light outlets in the corresponding light outlet group can also be sorted, and the corresponding light outlet group refers to a group composed of all the light outlets that have detected the same number and content of identifiers as the light inlets in the light inlet group. After the sorting is completed, the first light entrance in the light entrance group is used as a reference to determine the light exit port that has a connection relationship with the first light entrance port, that is, from the corresponding light exit group, find the detected The light output port whose corresponding optical power is greater than and closest to the corresponding optical power detected by the first light input port. Generally speaking, the difference between the power of an optical wavelength signal or an optical multiplex section signal when it passes through a certain optical inlet and the power when it passes through an optical outlet that is connected to this optical inlet should be less than 0.2dB, but considering factors such as detection accuracy It can be considered that the optical power difference can be less than 1dB. Therefore, the optical output port found should be the optical output port whose detected optical power is greater than the optical power detected by this optical input port, and the difference should be less than 1dB. It is the light exit port that is connected to the first light entrance port. In the same way, use other light entrances as a reference to determine the light exits that are connected to these light entrances. After the first light entrance group is determined, use the light entrances in other light entrance groups as a reference To determine the light outlets that have a connection relationship with the light entrances in these light entrance groups, so that the connection relationship between the light ports can also be determined.

It should be noted that if the difference in optical power corresponding to the optical input port and the optical output port at the same position in the sequence is too large, it can be further inferred that although there is an optical fiber connection relationship between the optical output port and the optical input port, the optical fiber connection may be affected by the optical fiber. The connection loss is too large due to pollution, damage, and poor connection of the end face of the jumper. If it is detected that the number of light exit ports and light entry ports with the same identification does not match, it can also be deduced which optical fiber connection behind the light exit port is abnormal.

In order to make it easier for those skilled in the art to understand the flow shown in FIG. 2 more clearly, the flow shown in FIG. 2 will be described below with an example of practical application. In this practical example, it is assumed that an optical network node has functional units A, B, and C, and the identifiers and corresponding optical powers detected by the optical entrances and exits of functional units A, B, and C are shown in Table 3 and Table 3 respectively. Table 4 shows:

table 3

Table 4

Summarize the light entrances and light exits that detect the same number and content of the logo into one group, and the summary results are as follows:

It is detected that the light entrance group of S1 and S3 is {light entrance 1 of functional unit B, light entrance 3 of functional unit C}, and the light exit group is {light exit 2 of functional unit A, light entrance 2 of functional unit B port 1};

It is detected that the light entrance group of S2 and S4 is {light entrance 2 of functional unit B, light entrance 1 of functional unit C}, and the light exit group is {light exit 3 of functional unit A, light entrance 1 of functional unit B mouth2};

It is detected that the light entrance group of S5 and S6 is {light entrance 3 of functional unit B, light entrance 2 of functional unit C}, and the light exit group is {light exit 1 of functional unit A, light entrance 1 of functional unit B Mouth 3}.

If it is determined that the light outlet is connected to the light entrance 1 of the functional unit B, then find the light entrance with the corresponding optical power that is relatively close to the optical power of the functional unit B from the group of light exits that detect S1 and S3 1 Larger optical outlet, if the corresponding optical power detected by the optical outlet 2 of the functional unit A is greater than the corresponding optical power detected by the optical entrance 1 of the functional unit B, and the corresponding optical power detected by the optical entrance 1 of the functional unit B is greater than that of the optical entrance of the functional unit B If the optical power detected in the light output port corresponding to the optical power of 1 is closest to the corresponding optical power detected by the light input port 1 of the functional unit B, then it can be determined that the light output port 2 of the functional unit A and the light input port 1 of the functional unit B have a connection relationship. The methods for determining the connection relationship of other optical ports can be deduced by analogy. In this way, the connections between all light inlets and light outlets of the functional units A, B and C can be determined.

In the second method of the present invention, only the optical signal source or the optical regeneration section source can be used to load the optical wavelength signal or the optical multiplex section signal, and it is not necessary for each optical outlet to load the passed optical wavelength signal or optical multiplex section signal. The marking avoids the loss introduced by the marking loading device and saves the cost of introducing the loading device.

The second method of the present invention can be realized by many forms of devices, one of which may include: an identification loading unit, used to load the optical wavelength signal or optical multiplex section signal issued by the optical signal source with an identification, or in the The source of the optical regeneration section loads a mark on the amplified optical wavelength signal or optical multiplex section signal; the mark detection unit is used for each optical entrance and A mark is detected on the light exit port; a connection relationship determination unit is configured to determine the connection relationship between the light exit port and the light entry port according to the mark matching and power matching relationship between the light exit port and the light exit port.

In practical applications, although more than two-stage amplifiers are rarely used to solve the power budget, there are still optical networks that use more than two-stage amplifiers to solve the power budget. In order to solve the problem of determining the connection relationship of optical ports in such optical networks, this paper The invention also provides a third method for determining the connection relationship between optical ports.

The overall technical solution of the third method of the present invention is as follows: on the optical signal source and the optical regeneration section source, mark the passed optical wavelength signal or optical multiplex section signal; The passed light entrance and light exit port detect the loaded logo; according to the detection result of the logo, determine the adjacent upstream and downstream relationship between the optical signal source and the light regeneration section source and between the light regeneration section sources, and determine the The optical inlet and outlet group in the same regeneration section; in the same regeneration section optical inlet and outlet group, according to the optical wavelength signal power or optical multiplexing section signal power detected by the optical outlet and the optical inlet Or identify the power relationship, and determine the connection relationship between the light exit port and the light entry port.

Wherein, the same number of marks detected at the light entrance and the light exit port and the same marks are regarded as the light entrance port and the light exit port group in the same regeneration section.

The frequency used for the identification, the spreading code, the identification ID information carried by the identification, or the time slot information corresponding to the identification correspond to the optical signal source or the optical regeneration section source one by one.

The connection relationship between the optical inlet port and the optical outlet port in the same regeneration section can be determined according to the following steps: according to the power of the optical wavelength signal detected by the optical inlet port, the power or the identification of the optical multiplex section signal The power of the optical entrance is sorted; according to the power of the optical wavelength signal detected on the optical exit, the power of the optical multiplex section signal or the power of the logo, the optical exit is added to the sequence of optical entrances ; If there is one and only one light outlet between the two adjacent light inlets, it is determined that there is a connection relationship between the light outlet and the light inlet that detects a lower power among the two light inlets; If the light entrance has one and only one light exit before the light entrance, it is determined that there is a connection relationship between the light exit and the light entrance.

The connection relationship between the optical inlet port and the optical outlet port in the same regeneration section can also be determined according to the following steps: according to the power of the optical wavelength signal detected by the optical outlet port, the power or the identification of the optical multiplex section signal The power of the optical outlets is sorted; according to the power of the optical wavelength signal detected on the optical entrance, the power of the optical multiplex section signal or the power of the logo, the optical entrance is added to the sequence of optical outlets ; If there is and only one light entrance between the two adjacent light exits, it is determined that there is a connection relationship between the light entrance and the light exit with higher power detected in the two light exits; if If the light outlet has one and only one light inlet behind the light outlet, then it is determined that there is a connection relationship between the light outlet and the light inlet.

The adjacent upstream and downstream relationship between the optical signal source and the optical regeneration section source and between the optical regeneration section sources can be determined in the following manner: The number of detected optical signal sources or optical regeneration section sources is sorted from the least to the most; The optical regeneration section source is adjacent to the downstream of the optical signal source or the optical regeneration section source.

Further, if it is determined that there is a connection relationship between the optical regeneration segment source detected with n identifiers and the optical signal source or optical regeneration segment source corresponding to a certain identifier among the n identifiers, it is determined that n+1 There is an adjacent upstream-downstream relationship between the optical regeneration segment sources of the different identifications and the optical regeneration segment sources corresponding to the different identifications, wherein, among the n+1 identifications, n identifications are related to the detected n identifications The n identifiers detected by the identified optical regeneration section source are completely the same, and n is an integer greater than 0; by analogy, the connection relationship between other optical regeneration section sources is determined.

The adjacent upstream and downstream relationship between optical regeneration section sources can be determined in the following manner: according to the identification detection results, sort according to the number of light outlet identifications of optical regeneration section sources detected by the light entrance of each optical regeneration section source; Comparing the marks detected by the light entrances of the two optical regeneration section sources whose detection numbers are greater than 1 and whose quantity differs by 1, if the marks detected by the light entrances of the two light regeneration section sources have and If there is only one difference, then the optical regeneration segment source with a large number of identification detections is located adjacent to the optical regeneration segment source corresponding to the different identification; for the optical regeneration segment source whose identification detection number is 1, then determine the The optical regeneration segment source is located adjacent to the downstream of the optical signal source or the optical regeneration segment source corresponding to the mark.

Further, if the power of the optical wavelength signal, the power of the optical multiplex section signal or the power of the logo detected on an optical outlet is different from the power of the optical wavelength signal detected on any optical entrance, the power of the optical multiplex section signal or If the marked power differences are greater than the preset power difference threshold, it is determined that the optical fiber connection relationship related to the optical outlet is abnormal.

Step S301: Marking the passed optical wavelength signal or optical multiplex section signal on the optical signal source and the optical regeneration section source.

The optical regeneration section source can change the optical power in the optical network. If the optical regeneration section source is marked on the optical wavelength signal or the optical multiplexing section signal passing through its optical outlet, the distance between the optical signal source and the adjacent optical regeneration section source , The optical power of the optical wavelength signal or the optical multiplexing section signal transmitted between two adjacent optical regeneration section sources and between the optical signal sink and the adjacent optical regeneration section source is decreasing, so that the entire optical network It is divided into several sections by the optical signal source, the optical regeneration section source and the optical signal sink, and the optical power of the optical wavelength signal or the optical multiplexing section signal transmitted in each section decreases gradually.

Step S302: The optical signal sink or each optical regeneration segment source determines the adjacent optical regeneration segment source or optical signal source by detecting the arriving identifier.

Although the optical wavelength signal or the optical multiplex section signal is transmitted between the optical signal source and its adjacent optical regeneration section source, between two adjacent optical regeneration section sources, and between the optical signal sink and the adjacent optical regeneration section source may pass through other optical network nodes or functional units, but since these optical network nodes or functional units only transfer optical wavelength signals or optical multiplex section signals, these optical network nodes or functional units can be equivalent to optical fibers for transmitting signals, so , step S302 can be realized by the process shown in Figure 1, except that the optical signal sink or each optical regeneration section source detects the optical signal source and the identification loaded by the optical regeneration section source, and finally determines the optical signal source, all Adjacent upstream and downstream relationships between regeneration segment sources and optical signal sinks.

Step S303: All optical inlets or outlets in each optical regeneration section detect all identifiers and corresponding optical power information in the arriving optical wavelength signal or optical multiplex section signal. This step may be the same as step S202.

Step S304: Summarize the corresponding relationships between the light entrances and light exits with the same number and contents of the detected signs and their detected information into one group. This step may be the same as step S203.

Step S305: Perform power matching on the optical ports of the same group, and the optical output port with the most power matching has a connection relationship with the optical input port. This step may be the same as step S204.

Specifically, for the light exit or light entrance in each group, in the light entrance group or light exit group that detects the same number and content of the logo, find the most matching optical power corresponding to the detected logo The light entrance or light exit, the light entrance or light exit that is found is the light entrance or light exit that has a connection relationship with it.

It should be noted that the process shown in FIG. 3 is only an implementation of the third method of the present invention. In practical applications, there may be multiple processes to realize the third method of the present invention. For example, the above step S301 The technical means that each optical signal source in the optical signal source loads an identifier in the emitted optical signal can be used in step S303, or step S302 and step S303 can be performed simultaneously.

In the third method of the present invention, the optical signal source, optical regeneration segment source and optical signal sink can divide the entire optical network into multiple sections. Specifically, the process shown in Figure 1 can be used to determine the optical signal source, optical For the adjacent upstream and downstream relationship between the regeneration segment source and the optical signal sink, use the process shown in Figure 2 to determine the connection relationship between all the optical ports in each section. Therefore, for an optical network with an optical regeneration segment source In other words, it is entirely possible to use the third method of the present invention to determine the connection relationship between optical ports.

The third method of the present invention can be realized by many forms of devices, one of which can include: an identification loading unit, which is used to record the passing optical wavelength signal or optical multiplexing section on the optical signal source and the optical regeneration section source The signal is loaded with an identification; the identification detection unit is used to detect the loaded identification at the optical entrance and the optical exit through which the optical wavelength signal or the optical multiplexing section signal passes; the upstream and downstream relationship and the optical port group determination unit are used Determine the adjacent upstream and downstream relationship between the optical signal source and the source of the optical regeneration section and between the sources of the optical regeneration section according to the result of the identification detection, and determine the light inlet and outlet groups in the same regeneration section; the connection relationship is determined A unit, configured to determine the output light according to the relationship between the optical wavelength signal power detected by the optical output port and the optical input port or the signal power of the optical multiplexing section or the identification power in the same group of the optical input port and the optical output port of the regeneration section. The connection relationship between the port and the light entrance.

All the methods and devices of the present invention can not only realize the determination of the optical port connection relationship between the optical network nodes, but also realize the determination of the optical port connection relationship between each functional unit in the optical network node.

If all the methods and devices of the present invention are used to determine the optical port connection relationship between each functional unit in an optical network node, then because each functional unit is relatively independent, electromagnetic interference (EMI) such as electric leakage and creepage can be avoided. , Electromagnetic Interference) problem.

All the methods and devices of the present invention use the identification as a basis for detecting the connection relationship, which can avoid the problem of inconsistency between the detection results and the actual business operation in the case of bypass detection, and can be performed without affecting the normal transmission of optical signals. , to determine the connection relationship between optical ports at any time.

In the process of using all the methods of the present invention, if the path-associated identification signal loaded by a certain optical outlet is not detected by the optical entrance of any functional unit in the optical network node or the optical entrance of other optical network nodes, It means that the optical fiber jumper connected to the optical outlet is faulty. In addition, if a certain optical entrance does not detect the optical entrance of any functional unit in the optical network node or the identification of the optical entrance of other optical network nodes , it means that the optical entrance is not connected with the optical entrance of any functional unit in the optical network node or the optical entrance of other optical network nodes, or that the optical fiber jumper connected to this optical entrance exists Fault. Therefore, all the embodiments of the method of the present invention can also judge whether the connection between the optical ports is normal, locate the point of failure, and the like.
