用于下线间无线序光缆割接的旧路由光缆法

The Old Route Fiber Optic Cable Method for Cut/Splice of Fiber Optic Cable without Fiber Sequence and between Branching Points

通过测试旧路由光缆,查找出旧路由光缆同机房侧光缆连接的光纤色谱线序信息,用于处理下线间无线序光缆割接难题。实践证明采用旧路由光缆法进行下线间无线序光缆割接可确保割接完毕后光路、线路直接通,两端光纤无需倒换,并且可按重要线路优先原则进行光缆路由变更。此外,旧路由光缆法还可用于处理光缆故障。

A difficult issue is solved for the cut/splice of fiber optic cable without fiber sequence and between branching points, which measures old route fiber optic cable to find out the fiber color sequence information at the connection of old fiber optic cable and the fiber optic cable at the equipment room side. The practice proves that this method can ensure the connection of optical loops and links after cut/splice of the fiber optic cable, and the fibers at both ends need not to be rearranged, moreover it is possible to change the cable route according to the priority of important links. Also old route fiber optic cable method can be used in dealing with cable default.
