Method for monitoring aging process of working state of optical module in real time

Abstract

The invention discloses a method for monitoring an aging process of a working state of an optical module in real time, and aims to provide a test device that is easy to operate, high in test efficiency, not easy to make mistakes, and can monitor the working state of the optical module in real time. The method is implemented by the following technical scheme: an interface circuit is connected in parallel with two microprocessors; the microprocessors communicate with a designated optical module communication bus through an analog switching circuit to collect data of an optical module under test;the interface circuit converts I2C communication into USB communication of the microprocessors, and transmits monitored aging information of the optical module to built-in automatic monitoring software of the microprocessors; and the automatic monitoring software performs real-time on-line monitoring and diagnosis on the working states of the optical modules on all burn-in boards, tests working performance parameters of the optical module under test all the time, automatically acquires eye diagram and test sensitivity information, masters the aging degree of each optical module, carries out fault diagnosis services, inquires and traces obtained optical module parameter information, and finds out positions of faults in a link.

Description

technical field [0001] The invention relates to a method for real-time monitoring of the working state aging process of a photoelectric conversion module in the field of optical communication networks during the production process. Background technique [0002] Optical fiber communication occupies a dominant position in modern information networks. As the coverage of the network becomes wider and wider and the communication capacity continues to increase, the management of communication links becomes more complicated. As the core device of the optical fiber access network, the optical transceiver module promotes the development of the trunk optical transmission system in the direction of low cost. An optical module is a photoelectric conversion module composed of optoelectronic devices, functional circuits, and optical interfaces. The optical module is mainly used for sending and receiving optical signals. The optical signal is connected to the optical module through an opt...
