Detailed ways

The technical scheme of the utility model will be further described below in conjunction with the accompanying drawings and through specific embodiments.

An optical fiber sequence and attenuation detector, comprising a signal transmission module, a hand-held terminal A wirelessly connected to the signal transmission module, a signal reception detection module, and a hand-held terminal B wirelessly connected to the signal reception detection module; the signal The sending module includes a main control chip MPU, and a light source connected to the MPU, an optical switch, an output interface and a wireless module; the signal receiving detection module includes a receiving identification port, a buffer and a wireless module connected to the receiving identification port; The handheld terminal A and the handheld terminal B have the same structure, including an MCU, and a wireless module and a display screen connected to the MCU; the output interface of the signal sending module is connected to the ODF frame of the communication site site one in sequence using a pigtail Above; the receiving identification port of the signal receiving and detecting module is connected to the corresponding ODF frame of station two in sequence.

The handheld terminal A is connected to the handheld terminal B in communication.

The working principle of the system is as follows: first, connect the pigtails of the output interface of the signal sending module to the new optical cable ODF frame of the communication site using the pigtails in sequence, and connect the detection module B to the corresponding ODF frame of the second site in sequence.

The signal sending module switches the light source to the output interface according to the sequence of the output interface. The MPU controls the sequential output of the optical label and the light source for 5S, and the next chip emits light at an interval of 1S. The receiving identification port of the signal receiving detection module detects the light of all ports in real time. data. According to the number of fiber cores, set the test receiving time, the time unit is second, to ensure complete testing of all fiber cores.

Test duration = 12X cable core.

Finally, the signal receiving and detecting module detects the optical data of all ports in real time and sends them to the handheld terminal B through the wireless module. The MCU of the handheld terminal B processes the data and displays it on the touch screen. Check whether there is a fiber sequence error by comparing whether the optical label is the same as the receiving port. At the same time, evaluate the attenuation of each core according to the optical power of the receiving identification port of the signal receiving detection module. If there is a receiving port that cannot receive optical power, then It shows that this core is a broken core.

The handheld terminal A communicates with the handheld terminal B to realize synchronous sharing of information. During the acceptance process after the completion of the new communication optical cable, if the two communication sites are relatively close, a group of professionals can complete the work and install the detector. Finally, the handheld terminal A receives the data processing display results of the handheld terminal B, that is, by comparing whether the optical label is the same as the receiving port, to detect whether there is a fiber sequence error, and at the same time evaluate according to the optical power of the receiving identification port of the signal receiving detection module The attenuation of each core, if there is a receiving port that cannot receive optical power, it means that the core is broken; the tester can adjust the line sequence according to the test results to make the line sequence of the optical fiber distribution frame connector at both ends correspond to each other. If the two communication points are far away, the two groups of personnel can adjust the line sequence according to the test results on the display screens of handheld terminal A and handheld terminal B to make the line sequence of the optical fiber distribution frame connectors at both ends correspond to each other.

The above is only the preferred embodiment of the utility model, it should be pointed out that for those skilled in the art, without departing from the overall concept of the utility model, some changes and improvements can also be made, and these should also be regarded as Protection scope of the present utility model.
