摘　　要：随着光通信网络的不断发展,光缆故障测试和排除成为一种广泛应用的新技术,要求维护人员准确定位,迅速排除。文章详细介绍了如何进行光缆故障点的准确定位,并对影响光缆线路障碍点判断的各种因素进行了较为详细的分析。最后根据光缆障碍点的测试要求,对操作维护人员提出了全面的解决方案。With the development of optical communication networks, the technology for cable fault location and shooting has become a widely used new technology, which requires that the service men locate and remove cable fault promptly. This paper presents the way to make accurate location of cable fault and analyses the factors affecting the location of cable fault. Finally, it presents a complete solution that meets the requirements of cable fault location for the service men.
