Embodiment Construction

[0028] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0029] figure 1 The schematic diagram of the application architecture of the embodiment of the present invention in WR-WDM-PON is shown. In a WR-WDM-PON 5G fronthaul application, the WR-WDM-PON includes the optical line terminal OLT, ODN and multiple ONUs.

[0030] The optical line terminal OLT in the embodiment of the present invention includes two optical module arrays, a channel switch control unit group respectively connected to the two optical module arrays, a management module, and a wavelength multiplexer WM.

[0031] Each optical module in the first optical module array and the second optical module array is used for photoelectric conversion of signals received and sent by the optical module. For clarity, the optical modules in the first optical module array are referred to as first optical modules, and the optical modules i...

Abstract

The invention discloses an optical line terminal and a service channel mirror method, which relate to the technical field of communication. According to the optical line terminal, each optical modulein a first optical module array is connected with a service unit through a service node interface (SNI), and each optical module in a second optical module array is connected with a wavelength multiplexer (WM); a channel switch control unit group comprises two channel switch control units, each channel switch control unit is provided with multiple input ports and output ports, and the input portsand the output ports are connected with the optical modules in different optical module arrays; and a management module is used for issuing configuration information of the input ports and the outputports to the two channel switch control units so as to build a two-way service channel and a service channel mirror channel between the SNI and a user network interface (UNI). After a service application fails, the service data information can be acquired from the mirror channel to analyze and position the fault, and the service channel is monitored and managed.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to an optical line terminal and a service channel mirroring method. Background technique [0002] Wavelength Division Multiplexing-Passive Optical Network (WDM-PON) consists of optical line terminal (optical line terminal, OLT), optical distribution network (Optical Distribution Network, ODN) and optical network unit (Optical Network Unit, ONU) ), wherein the ODN includes an optical fiber feeder section, a wavelength multiplexer (Wavelength Multiplexer, WM) and a branch optical fiber. [0003] In wavelength routed wavelength division multiplexing passive optical network (Wavelength Routed Wavelength Division Multiplexing-Passive Optical Network, WR-WDM-PON), WM is a WR-WDM-PON wavelength channel pair and channel group Bi-directional functional unit providing multiplexing / demultiplexing functions. Through the different wavelengths of the WM branch in the ODN, the working wave...
