Description

Uplink signal transmission method, device, equipment, storage medium and program product
Technical Field

Background
The existing Network EPON (ETHERNET PASSIVE Optical Network) system comprises 10G-EPON and 50G-PON, most of EPON terminals have uplink wavelengths which are not narrowed (1260 nm-1360 nm), and all conflict with three uplink wavelength options defined by the 50G-PON (Passive Optical Network ) standard, so that uplink time division technology is required to achieve coexistence of the EPON, 10G-EPON and 50G-PON with ODN (Optical Distribution Network ) of the third generation system. Because the uplink rates of different generation-based PONs are greatly different, the practical uplink bandwidth of the 50G-PON is greatly limited by the mode, the ultra-high uplink capacity of the 50G-PON cannot be fully exerted, and the service requirements of high-value clients cannot be met.
As the EPON terminal continues to drop out of the network, it eventually evolves into two generations of coexistence of 10G-EPON and 50G-PON. Since the 10G-EPON and the 50G-PON have no wavelength conflict, the method can be restored to an uplink wavelength coexistence (WAVELENGTH MULTIPLEXING COEXISTENCE) mode, the respective uplink bandwidths are not mutually influenced, and the advantage of the capability of the 50G-PON for the uplink super-large bandwidth is restored.
However, if the existing architecture needs to be restored to the coexistence of uplink wave components, the OLT needs to be replaced, and the cost expenditure is high.

Detailed Description
The present application will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present application more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the application.
Before the technical scheme of the embodiment of the application is specifically introduced, the technical background or technical evolution context based on the embodiment of the application is introduced.
The 50G-PON is a key technology for realizing a base of a 'tera' optical access network, and is also a core technology for guaranteeing sustainable evolution of an operator in a very large scale 10G-PON and continuously providing higher-speed broadband access capability. The 50G-PON is used as a next-generation high-speed PON technology, can provide flexible high-speed bandwidth access capability for cloud network fusion new application, virtual Reality (VR), augmented Reality (Augmented Reality, AR), machine vision, metauniverse, digital twin and other scenes, and further improves the digital level of the whole society.
The 50G-PON system architecture supports rate combining of multiple ONUs (Optical Network Unit, optical network units), such as asymmetric 50G/12.5G, asymmetric 50G/25G, symmetric 50G/50G, by using upstream TDMA (Time Division Multiple Access )/downstream TDM (Time Division Multiplex, time division multiplexing).
The existing network EPON system comprises EPON and 10G-EPON, and the coexisting evolution of 50G-PON is required. However, most EPON terminals have their upstream wavelengths not narrowed (1260 nm to 1360 nm) and occupy the upstream and downstream wavelength ranges of 50G-PON. In addition, the uplink wavelength of the 10G-EPON terminal of the existing network is various due to different standards referenced in different periods, and the uplink wavelength of the asymmetric 10G-EPON terminal conforming to the IEEE standard is 1260-1360 nm and cannot coexist with the 50G-PON. As shown in fig. 1, the wavelengths of the EPON and 10G-EPON terminals of the existing network are narrowed and not narrowed, and have a conflict relationship with the uplink and downlink wavelengths of the 50G-PON. Therefore, the coexistence of EPON/10GE-PON and 50G-PON is currently realized based on an uplink time division multiplexing mode.
With the further promotion of gigabit broadband construction and popularization work, the natural gradual network withdrawal of the existing network EPON terminal is a necessary process. As the EPON terminal continuously exits the network, the two generations of coexistence of 10G-EPON and 50G-PON are finally developed, and as the 10G-EPON and 50G-PON have no wavelength conflict, the coexistence mode of uplink wavelength components can be restored theoretically, the respective uplink bandwidths are not affected, and the advantage of the capability of the uplink ultra-large bandwidth of the 50G-PON is restored.
However, if the existing architecture needs to be restored to the coexistence of upstream components, the OLT (Optical LINE TERMINAL) needs to be replaced, and the cost is relatively high.
In view of the above problems, an embodiment of the present application provides an uplink receiving system. The uplink receiving system introduces a mode selection module, a time division routing module and a branching switch module, and the cost expenditure of the modules is small, so that the uplink receiving system can realize smooth switching of coexistence of two generations of wave division of 10G-EPON/50G-PON after the EPON terminal is disconnected, and can fully exert higher uplink bandwidth capacity of 10G-EPON and 50G-PON.

Then, the mode selection module 11 outputs a 50G-PON upstream electrical signal to the time division routing module 12 and outputs a 10G-EPON upstream optical signal to the branching switch module 13.
The time division multiplexing module 12 receives the second wavelength division control signal and the 50G-PON upstream signal, cuts off the communication connection with the branching switching module 13 according to the second wavelength division control signal, and outputs the 50G-PON upstream signal.
The branching switch module 13 receives the third wavelength division control signal and the 10G-EPON uplink electrical signal, and outputs the 10G-EPON uplink electrical signal according to the third wavelength division control signal.

In the technical scheme of the embodiment of the application, the uplink receiving system is introduced with the mode selection module, the time division routing module and the branching switch module, and the cost expenditure of the modules is smaller, so that the uplink receiving system can realize the smooth switching of coexistence of two generations of wave division facing to 10G-EPON/50G-PON after the EPON terminal is disconnected, and can fully exert higher uplink bandwidth capacity of 10G-EPON and 50G-PON.

In the embodiment of the application, the access network management system stores the terminal information of the EPON terminal, the 10G-EPON terminal and the 50G-PON terminal, and if the EPON terminal is determined not to be out of the network according to the terminal information, the uplink receiving system is determined to transmit signals in a time division coexistence mode. In this case, the access network management system transmits the first time division control signal to the mode selection module 11 of the uplink reception system, the second time division control signal to the time division routing module 12, and the third time division control signal to the branching switch module 13, respectively.
It should be noted that, the access network management system may send the first time division control signal, the second time division control signal, and the third time division control signal at the same time, or may send the first time division control signal, the second time division control signal, and the third time division control signal in a preset order.

Thereafter, the time division routing module 12 outputs the first uplink electrical signal according to the uplink time slot scheduling assignment information acquired in advance, or transmits the second uplink electrical signal to the branching switch module 13.
