Research on Minimum OTDR Full Coverage Search Strategy Based on Optical Cable Value in Intelligent Optical Distribution System

结合智能光配系统的光纤芯跳接功能,电力通信光缆网络可通过部分OTDR监测点实现全网的故障检测。文章研究了在电力通信光缆网中,通过合理选取OTDR监测点,实现用最少的OTDR节点覆盖全区域内光纤芯性能检测。搭建了基于光缆价值量的网络模型,提出完全随机搜索策略、最长距离优先搜索策略和最高价值优先搜索策略,并给出智能光缆网络中OTDR节点选取的解决方案。

Combining with the optical fiber core hopping function of intelligent optical distribution system,the power communication optical cable network can realize the fault detection of the whole network through some OTDR monitoring points.This paper studies how to realize the optical fiber core performance detection of the whole network by using minimum OTDR nodes through reasonable selection of OTDR monitoring points.A network model based on the value of optical cable is built,the completely random search strategy,the longest distance first search strategy and the highest value first search strategy are proposed,the solution of OTDR nodes selection in intelligent optical cable network is provided.
