摘要
DWDM误码问题涉及因素多,定位复杂,是运维工作的难点。以某传输干线DWDM网络运行与误码维护实例为背景,论述波道误码问题的产生原因及基本排查思路,重点分析端面反射对DWDM系统的影响和解决方法。
DWDM error code involves in various factors and high complexity of pinpointing and is a diffi- cult point in operation and maintenance. In a certain maintenance case of transport trunk DWDM network error, this article discusses the causes and basic troubleshooting process of channel code error and focuses on the analysis of the impact of end reflection on DWDM systems and solutions.
