摘要
从SDH系统帧结构出发,介绍了B1,B2,B3,V5四种误码帧字节开销功能,重点说明了引起SDH光纤传输系统误码的5个主要因素,分析了10 Gbit/s速率光设备误码问题的处理方法,并结合河南电网主干传输网姚孟电厂至左寨变10 G光设备误码产生的原因,阐述了SDH光传输设备误码问题的处理方法和思路,供光纤通信技术人员参考。
This paper introduces four kinds of BER frame overhead functions： B1, B2, B3 and V5. It analyzes five main reasons causing the transmission error in optical SDH system and puts forward the processing methods for optical equipment BER at 10 G. By analyzing the transmission error in Henan power grid, some suggestions for dealing with optical SDH transmission errors are made for reference.
