摘　　要：通过对多支路链接并且纤芯少的光缆故障分析,光缆使用时间过久,没有进行大修的光缆接头,由于光纤模场直径大小不同而产生劣变,导致只能单方向传送光信号的现象。根据光在光纤中的传输原理,实践将2个变电站之间的纤芯收发互换,可以继续使用,较好地解决了光缆芯数少、光纤资源不足带来的矛盾,同时可以解决光缆多支路链接的单通道没有迂回光缆路由的问题。By using the principle of light transmission in optical fiber, this paper analyzed the faults of multi-drop link and lack of fiber core on fiber cable. If an optical cable has been used for a long time and its cable joint has not been maintained, it may lead to deterioration and single way transmission, due to different mode field diameters of fibers. Based on this principle, we could follow the practical example to exchange the fiber core transceivers between two substations, making them still useful. It solved the problem of lack of fiber core. At the same time, it made the single channel for multi-drop link possible, and solved the problem of alternate route in optical cable.
