Description

Technical Field

[0001] The present application relates to the field of signal transmission technology, and in particular to an uplink signal transmission method, device, equipment, storage medium and program product. Background Art

[0002] The existing EPON (Ethernet Passive Optical Network) system includes 10G-EPON and 50G-PON. The upstream wavelength of most EPON terminals is not narrowed (1260nm~1360nm), which conflicts with the three upstream wavelength options defined in the 50G-PON (Passive Optical Network) standard, resulting in the need for upstream time division technology to achieve the coexistence of the same ODN (Optical Distribution Network) of the three generations of EPON, 10G-EPON and 50G-PON systems. Due to the large difference in the upstream rates of different generations of PON, this model greatly limits the actual upstream bandwidth of 50G-PON, and it cannot give full play to its ultra-high upstream capabilities and meet the business needs of high-value customers.

[0003] As EPON terminals continue to be withdrawn from the network, the two generations of 10G-EPON and 50G-PON will eventually coexist. Since there is no wavelength conflict between 10G-EPON and 50G-PON, they can be restored to the upstream wavelength division coexistence mode, and their upstream bandwidths will not affect each other, restoring the advantage of 50G-PON's upstream ultra-large bandwidth capability.

[0060] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0061] Before specifically introducing the technical solutions of the embodiments of the present application, the technical background or technical evolution context on which the embodiments of the present application are based is first introduced.

[0062] 50G-PON is a key technology for realizing the foundation of "10 Gigabit" optical access network, and is also a core technology to ensure the sustainable evolution of operators' ultra-large-scale 10G-PON and continue to provide higher-speed broadband access capabilities. As the next generation of high-speed PON technology, 50G-PON can provide flexible and high-speed bandwidth access capabilities for new cloud-network integration applications, virtual reality (VR), augmented reality (AR), machine vision, metaverse, digital twins and other scenarios, further improving the digital level of the entire society.

[0063] The 50G-PON system architecture adopts upstream TDMA (Time Division Multiple Access) / downstream TDM (Time Division Multiplex) and supports multiple ONU (Optical Network Unit) rate combinations, such as asymmetric 50G / 12.5G, asymmetric 50G / 25G, and symmetric 50G / 50G.

[0064] The existing EPON system includes EPON and 10G-EPON, and there is a need for coexistence and evolution with 50G-PON. However, the upstream wavelength of most EPON terminals has not been narrowed (1260nm~1360nm), occupying the upstream and downstream wavelength range of 50G-PON. In addition, the 10G-EPON terminals in the existing network have different upstream wavelengths due to different reference standards at different times. The asymmetric 10G-EPON terminals that follow the IEEE standard have an upstream wavelength of 1260~1360nm and cannot achieve wavelength division coexistence with 50G-PON. Figure 1 As shown in the figure, the wavelengths of existing EPON and 10G-EPON terminals are narrowed or not, which conflicts with the upstream and downstream wavelengths of 50G-PON. Therefore, the coexistence of EPON / 10GE-PON and 50G-PON is currently achieved based on the time division multiplexing method in the upstream direction.

[0065] With the further advancement of Gigabit broadband construction and popularization, the natural and gradual withdrawal of existing EPON terminals is an inevitable process. As EPON terminals continue to withdraw from the network, it will eventually evolve into the coexistence of 10G-EPON and 50G-PON. Since there is no wavelength conflict between 10G-EPON and 50G-PON, in theory, it can be restored to the upstream wavelength division coexistence mode, and the upstream bandwidth of each does not affect each other, restoring the advantage of 50G-PON upstream ultra-large bandwidth capability.

[0066] However, if the existing architecture needs to be restored to upstream wavelength division coexistence, the OLT (Optical Line Terminal) needs to be replaced, which is very costly.

[0067] 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 branch switch module, which have a relatively low cost expenditure. Not only can the uplink receiving system achieve smooth switching for the coexistence of 10G-EPON / 50G-PON two generations of wavelength division after the EPON terminal is decommissioned, but it can also give full play to the higher uplink bandwidth capabilities of 10G-EPON and 50G-PON.

[0068] The technical solutions involved in the embodiments of the present application are introduced below.

[0069] In an exemplary embodiment, Figure 2 As shown, an uplink receiving system is provided. The uplink receiving system includes a mode selection module 11, a time division routing module 12 and a branch switch module 13, and the mode selection module 11, the time division routing module 12 and the branch switch module 13 are respectively connected to the access network management system (the access network management system is not shown in the figure); the mode selection module 11 is used to perform wavelength division processing on the uplink optical signal according to the first wavelength division control signal, and output the first uplink electrical signal and the second uplink electrical signal; the first uplink electrical signal and the second uplink electrical signal correspond to uplink optical signals of different wavelengths; the time division routing module 12 is used to disconnect from the branch switch module 13 according to the second wavelength division control signal, and receive and output the first uplink electrical signal; the branch switch module 13 is used to receive and output the second uplink electrical signal according to the third wavelength division control signal; wherein the first wavelength division control signal, the second wavelength division control signal, and the third wavelength division control signal are all sent after the access network management system determines to adopt the wavelength division coexistence mode to transmit the signal.

[0070] In the embodiment of the present application, the access network management system stores the terminal information of the EPON terminal, the 10G-EPON terminal and the 50G-PON terminal, and after determining that all EPON terminals are off the network according to the terminal information, it is determined that the uplink receiving system can adopt the wavelength division coexistence mode to transmit signals. In this case, the access network management system sends a wavelength division control signal to the uplink receiving system.

[0071] The uplink receiving system may include a mode selection module 11, a time division routing module 12 and a branch switch module 13. The mode selection module 11, the time division routing module 12 and the branch switch module 13 are respectively connected to the access network management system for communication. When sending a wavelength division control signal, the access network management system sends a first wavelength division control signal to the mode selection module 11, sends a second wavelength division control signal to the time division routing module 12, and sends a third wavelength division control signal to the branch switch module 13.

[0072] It should be noted that the access network management system can send the first wavelength division control signal, the second wavelength division control signal, and the third wavelength division control signal at the same time, or it can send the first wavelength division control signal, the second wavelength division control signal, and the third wavelength division control signal in a preset order. The embodiment of the present application does not limit this and can be set according to actual conditions.

[0073] The mode selection module 11 of the uplink receiving system receives the first wavelength division control signal and the uplink optical signal, performs wavelength division processing on the uplink optical signal according to the first wavelength division control signal to obtain uplink optical signals of different wavelengths, and then performs photoelectric conversion processing on the uplink optical signals of different wavelengths to obtain a first uplink electrical signal and a second uplink electrical signal.

[0074] The time division routing module 12 of the uplink receiving system receives the first uplink electrical signal and the second wavelength division control signal, disconnects the communication connection between the time division routing module 12 and the branch switch module 13 according to the second wavelength division control signal, and outputs the first uplink electrical signal.

[0075] The branch switch module 13 of the uplink receiving system receives the second uplink electrical signal and the third wavelength division control signal, and outputs the second uplink electrical signal according to the third wavelength division control signal.

[0076] Taking the case where the upstream optical signal includes a 50G-PON upstream optical signal and a 10G-EPON upstream optical signal after the EPON terminal is de-networked as an example, the mode selection module 11 receives the first wavelength division control signal and the upstream optical signal, performs wavelength division processing on the upstream optical signal according to the first wavelength division control signal to obtain a 50G-PON upstream optical signal and a 10G-EPON upstream optical signal, and performs photoelectric conversion processing on the 50G-PON upstream optical signal and the 10G-EPON upstream optical signal to obtain a 50G-PON upstream electrical signal and a 10G-EPON upstream electrical signal. Afterwards, the mode selection module 11 outputs the 50G-PON upstream electrical signal to the time division routing module 12, and outputs the 10G-EPON upstream optical signal to the branch switch module 13.

[0077] The time division routing module 12 receives the second wavelength division control signal and the 50G-PON upstream electrical signal, cuts off the communication connection with the branch switch module 13 according to the second wavelength division control signal, and outputs the 50G-PON upstream electrical signal.

[0078] The branch switch module 13 receives the third wavelength division control signal and the 10G-EPON upstream electrical signal, and outputs the 10G-EPON upstream electrical signal according to the third wavelength division control signal.

[0079] In the above embodiment, the uplink receiving system includes a mode selection module, a time division routing module and a branch switch module. The mode selection module performs wavelength division processing on the uplink optical signal according to the first wavelength division control signal, and outputs a first uplink electrical signal and a second uplink electrical signal; the first uplink electrical signal and the second uplink electrical signal correspond to uplink optical signals of different wavelengths; the time division routing module disconnects from the branch switch module according to the second wavelength division control signal, receives and outputs the first uplink electrical signal; the branch switch module receives and outputs the second uplink electrical signal according to the third wavelength division control signal. In the technical solution of the embodiment of the present application, the uplink receiving system introduces a mode selection module, a time division routing module and a branch switch module. The cost expenditure of these modules is relatively small, which can not only enable the uplink receiving system to achieve smooth switching for the coexistence of two generations of wavelength division of 10G-EPON / 50G-PON after the EPON terminal is delisted, but also give full play to the higher uplink bandwidth capabilities of 10G-EPON and 50G-PON.

[0080] In an exemplary embodiment, Figure 3As shown, the mode selection module 11 is used to convert the uplink optical signal into a total uplink electrical signal according to the first time division control signal; the time division routing module 12 is used to perform time division processing on the total uplink electrical signal according to the second time division control signal to obtain the first uplink electrical signal and the second uplink electrical signal, and to conduct the connection with the branch switch module 13, and output the first uplink electrical signal or transmit the second uplink electrical signal to the branch switch module 13 according to the uplink time slot scheduling allocation information; the branch switch module 13 is used to receive and output the second uplink electrical signal according to the third wavelength division control signal; wherein the first time division control signal, the second time division control signal, and the third time division control signal are all sent after the access network management system determines to adopt the time division coexistence mode to transmit the signal.

[0081] In the embodiment of the present application, the access network management system stores the terminal information of the EPON terminal, the 10G-EPON terminal and the 50G-PON terminal. If it is determined according to the terminal information that the EPON terminal has not been de-networked, it is determined that the uplink receiving system adopts the time division coexistence mode to transmit the signal. In this case, the access network management system sends a first time division control signal to the mode selection module 11 of the uplink receiving system, sends a second time division control signal to the time division routing module 12, and sends a third time division control signal to the branch switch module 13.

[0082] It should be noted that the access network management system can 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 it can send the first time-division control signal, the second time-division control signal, and the third time-division control signal in a preset order. The embodiment of the present application does not impose any restrictions on this and can be set according to actual conditions.

[0083] The mode selection module 11 receives the first time division control signal and the uplink optical signal. Then, the mode selection module 11 converts the uplink optical signal into a total uplink electrical signal according to the first time division control signal.

[0084] The time division routing module 12 receives the second time division control signal and the total uplink electrical signal, switches on the communication connection with the branch switch module 13 according to the second time division control signal, and performs time division processing on the total uplink electrical signal according to the second time division control signal to obtain the first uplink electrical signal and the second uplink electrical signal. Afterwards, the time division routing module 12 outputs the first uplink electrical signal according to the uplink time slot scheduling allocation information acquired in advance, or transmits the second uplink electrical signal to the branch switch module 13. The uplink time slot scheduling allocation information is used to indicate the operation mode of the time division routing module 12, which includes the time range of each time slice, and the signal type output by each time slice.

[0085] The branch switch module 13 receives the third wavelength division control signal and the second uplink electrical signal, and outputs the second uplink electrical signal according to the third wavelength division control signal.

[0086] Taking the case where the EPON terminal has not been de-networked and the uplink optical signal includes at least two of the EPON uplink optical signal, the 10G-EPON uplink optical signal and the 50G-PON uplink optical signal as an example, the mode selection module 11 receives the first time division control signal and the uplink optical signal, and then converts the uplink optical signal into a total uplink electrical signal according to the first time division control signal, and outputs the total uplink electrical signal. The total uplink electrical signal includes at least two of the EPON uplink electrical signal, the 10G-EPON uplink electrical signal and the 50G-PON uplink electrical signal.

[0087] The time division routing module 12 receives the second time division control signal and the total uplink electrical signal, and outputs the 50G-PON uplink electrical signal in the first time slice according to the uplink time slot scheduling allocation information, and outputs the EPON uplink electrical signal or the 10G-EPON uplink electrical signal to the branch switch module 13 in the second time slice. Alternatively, the time division routing module 12 outputs the 50G-PON uplink electrical signal in the first time slice according to the uplink time slot scheduling allocation information, outputs the EPON uplink electrical signal to the branch switch module 13 in the second time slice, and outputs the 10G-EPON uplink electrical signal to the branch switch module 13 in the third time slice. For example, the time division routing module 12 outputs a 50G-PON upstream electrical signal in the t0 time slice according to the upstream time slot scheduling allocation information, outputs a 10G-EPON upstream electrical signal to the branch switch module 13 in the t1 time slice, and outputs an EPON upstream electrical signal to the branch switch module 13 in the t2 time slice; thereafter, the signals are output in the t3...ti time slices in the above order.
