Research on a passive submarine optical cable route detection technology

海缆的路由探测和故障点定位技术是海缆维护工作中的关键技术之一。文章针对目前常用探测方法的缺点和不足,提出了被动式海缆路由探测技术。首先介绍了被动式海缆路由探测的系统原理,然后在此基础上提出了该系统的设计方案,最后,给出了该系统的有效仿真方法及仿真结果。仿真结果表明:电压衰落斜率越大,线圈与光缆间的距离越远。因此被动式海缆路由探测系统可有效地对海缆进行路由跟踪和定位。

The route detection and fault location technology for submarine optical cables is one of the key technologies in undersea cable maintenance. In view of the shortcomings and insufficiency of the present commonly used detection methods, this pa per proposes a passive submarine optical cable route detection technology. It introduces its system principle, presents the design scheme and gives the effective simulation method and simulation results. The results indicate that the larger the voltage decline slope, the farther the distance between the coil and the cables, enabling the system to effectively carry on route tracking and fault location.
