基于FPGA的光收发器监测技术研究OACSTPCD

A large number of optical transceivers are used in relay protection equipment for communication within and between devices.At present,the failure of optical transceivers can be mainly divided into two situations,and there are mature countermeasures for the complete failure of relay protection equipment.However,its incomplete failure may lead to serious problems such as single frame flashing of communication messages,false alarms,and network congestion,affecting the normal operation of relay protection equipment and having adverse effects on the entire system.This article focuses on the issue of incomplete failure of optical transceivers,and designs an optical port data monitoring mechanism based on FPGA chips to avoid the problem of abnormal optical transceivers leading to reduced reliability of relay protection equipment.A switching scheme is designed for the dual monitoring link,achieving seamless connection between A and B system monitoring.Finally,the effectiveness of the scheme is verified on the hardware platform.
