摘要
介绍了一起光缆故障的现象和故障处理过程,分析了故障发生的原因。结果表明,光缆接续盒进水结冰,能够引起光缆衰耗急剧增加,造成传输中断;随着气温在0℃上下波动,光缆传输会时断时续。这起故障的分析处理,对于我国北方地区的光纤运行维护具有一定的借鉴意义。
This paper discusses an OPGW malfunction, analyzes its mechanism and introduces the treatment process. The result shows that signal attenuation increasing caused by water frozen in optical cable joints can lead transmission interruption. When the environment temperature fluctuates around 0℃ , the transmission is not stable. It has some reference value for OPGW operation and maintenance in north part of China.
