处置光缆割接所引发SDH（STM-64）误码的浅谈

摘要

通过对传输线路光缆割接所引起的10G SDH光传输设备的误码告警的排查、研究，认识与分析了Metro 5000（华为）设备SL64板件的性能指标，并将两者结合，加以总结归纳。讨论了光纤链路中的“再生段背景误码块”、“再生段误码秒”、“复用段背景误码块”、“复用段误码秒”的产生机制，阐述了日常光缆割接对光链路造成的误码影响，以及相对应的问题处理方法与思路，为此类传输故障排查、定位与解决方案的制定提供参考。%Through checking and researching on the error code alarm of 10G SDH optic-transfer equipment caused by cutting and connecting ifber optic, and studying and analyzing the performance index of Metro 5000 (HUAWEI) equipment’s SL64 plate, the results are combined and summarized. The generation mechanism of RSBBE, RSES, MSBBE, MSES in the optic-ifber link was discussed. The paper explicated how daily cutting and connecting of optic ifber cable can cause error code of optic-link, including how to solve the problem and how to think, providing reference for checking, locating and making resolution to remove this type of optic transfer fault.
