摘　　要：多功能光万用表是光纤链路现场测试的主要工具。在工程的现场测试中,为了使光纤测试的时间更短,所用仪表更少,方法更加简便,文章在传统的光万用表的基础上,增加了光的回波损耗测试和插入损耗测试的功能,同时,利用波分复用技术,实现所测数据的双向传输,并且在同一测试过程中还可以获取光纤长度的测量值。最后,通过样机在工程实际应用中的具体参数,证明了在链路的两端,光纤连接未断开的情况下即可进行双向测试,同时,也对多功能光万用表的未来发展进行了展望,对其应用提供了思路和建议。The multi-functional optical multi meter is the main tool of fiber link field test. In the field test, in order to make the fiber test time shorter, the instrument less, the method more convenient. On the basis of the traditional optical multi meter, this paper increases the function of return loss （RL） test and insertion loss （IL） test, realizes the bidirectional transmission of the test data by the wavelength division multiplexing technology, and obtains the measured value of fiber length in the same test process. Finally, through the parameters of actual prototype, this paper proves that the meter could make the bidirectional testing in optical fiber connecting. Then discusses its future development and provides the ideas and suggestions of its future application.
