摘要
从OTDR的测试原理出发,对怎样更精确地测试光纤长度、接头损耗等问题进行分析,并结合平时的工作经验,探讨光纤链路的维护与管理方法。
This paper deduces the measurement theories of OTDR and discusses the measure to make the test more accurately.Combined with work experience,as well as the OTDR test graphs,maintenance and manage-ment methods of fiber links are also discussed in this paper.
