摘要
目前,光纤网络在电力通信网中占据主导地位。为了检测电力光纤网络是否满足传输继电保护信号的要求,作者利用常用仪表进行了测试实验,并对专用光纤和复用光纤保护通道的传输性能进行了研究,提出了多种测试方法。这些方法也为新建和改造电力光纤通信工程的规划、设计和优化提供了参考。
Nowadays the optical fiber transmission network is playing an important role in power communication network. In order to judge whether the power optical fiber network can satisfy the requirements of transmitting relay protection signal, the author launched a trail by using ordinary testing instruments. In this paper, the author discusses the transmission performances of dedicated and multiplexing fiber protection channel and proposes several kinds of testing methods. These methods also provide the reference for layout, design and optimization when constructing and upgrading electric power optical fiber communication network.
