Digital diagnosis information acquisition method and device and optical module

Abstract

The embodiment of the invention provides a digital diagnosis information acquisition method and device and an optical module, and belongs to the technical field of optical fiber communication. According to the method provided by the embodiment of the invention, the instruction for acquiring the digital diagnosis information is triggered to be sent outwards through the word diagnosis information acquisition enabling flag bit, and the instruction is loaded into the emergent light in a low-frequency modulation signal mode and does not conflict with a normal data communication service; when the accurate digital diagnosis information is received, a success flag bit is obtained through the digital diagnosis information to prompt an upper computer to read, after the upper computer reads, the success flag bit is obtained through the digital diagnosis information to prompt an optical module to obtain the digital diagnosis information, and the optical module modifies the digital diagnosis information to obtain an enable flag bit so as to stop the execution of the method. According to the technical scheme provided by the embodiment of the invention, the digital diagnosis information of the far-end optical module can be obtained.

Description

technical field [0001] The present application relates to the technical field of optical communication, and in particular to a method, device and optical module for acquiring digital diagnostic information. Background technique [0002] In the access network communication system, an optical connection is established between the optical line terminal and the optical network unit to realize data communication. Specifically, the optical line terminal has a first optical module, and the optical network unit has a second optical module, and an optical connection is established between the first optical module and the second optical module; the optical line terminal communicates with the second optical module through the first optical module The module sends optical signals to realize that the optical line terminal sends data to the optical network unit; the optical line terminal receives the optical signal from the second optical module through the first optical module, and reali...

Problems solved by technology

In the physical network of the access network, the optical line terminal and / or the optical network unit are often located in an environment that is not convenient for manual operation, such as mountains, forests or even water bodies. Operating the host computer or using the host computer to control the optical module in these environments is difficult. become very difficult
