浅谈SDH光传输系统故障处理中故障定位的思路和方法

Optical SDH Transmission System Fault Fault Locating in the Treatment of the Ideas and Methods

在光传输系统中故障点的判断和处理直接关系到光传输系统的应用和稳定,其故障定位的思路一般为:先外部、后传输。也就是说在故障定位时,先排除外部的可能因素,如光纤断裂、交换故障、电源中断等,接着再考虑传输设备。

In optical transmission system fault judgement and processing directly related to the application of optical transmission system and stable, the fault location is generally thought： first, after transmission. Or in other words, to exclude fault locating the external factors, such as fiber fracture may malfunction, power supply, switching, then consider transmission equipment.
