摘　　要：光纤线路扩容是电力光纤通信网络发展的一项重要内容。本文根据光偏振原理将SDM100单纤双向传输转换器通过各种端口连接置于光路中,使原有的纤芯容量得到了提高。这项技术产品已在湖北黄冈地区投入试运行,效果良好。本文着重对SDM100在电力通信系统中的试验应用,包括端口连接、光纤通道链路连接、光纤通道环路连接方式作了介绍,并对该设备在支路、环路中的具体应用,进行了解释说明。Capacity expansion of optical fiber lines is quite important for electric power optical fiber communication network. According to the principle of light polarization, this paper introduces the method to enlarge the capacity by connecting bi-directional SDM100 single fiber transceiver to optical circuit. This technology has been applied in Huanggang district in Hubei Province and a- chieves good effect. Some applications of SDM100 in electric power communication system, such as terminal connection, optical fi- ber link connection and optical fiber loop connection are also discussed and explained in the paper.
