摘　　要：本文首先综述了光时域反射技术(OTDR)在国内外的发展现状,并阐述了OTDR基于背向瑞利散射的基本原理,重点介绍了OTDR技术在电力领域的应用,分析了当前市面上OTDR产品的性能比较,发现这些商用的OTDR在电力系统的应用有着一些自身的限制。因此针对电力领域的光纤链路监测,开发一种比较适合的OTDR系统可以在很大程度上解决光纤通信运营健康状况问题,并以实例证明了OTDR技术是光纤光缆链路故障点诊断和定位的有效手段。In this paper,it elaborated development status of Optical Time Domain Reflection（OTDR） at home and abroad,and the basic principles based on backward Rayleigh scattering,it highlighted OTDR technology in the field of electricity.Based on analysis for the difference of the current market OTDR products about their performance,we found that commercial OTDR applicated in the power system has some restrictions.For Fiber link monitoring for the power sector,a more suitable OTDR system was developed,which can largely solve the problem of the health status of fiber optic communications operator.The examples proved that the OTDR technology is the effective method to diagnosis and localization failure point of the fiber optic cable link.
