摘　　要：传统的光纤复用保护通道需将保护装置发出的光信号通过光电转换设备变成电信号后再复用进SDH传输,对端也需将收到的电信号转换成光信号后送到保护装置。这种方式增加了中间转换环节,致使信号传输效率低、时延较大、故障隐患较多。针对上述问题,设计了一种基于2M光接口的光纤复用保护通道,省去中间转换环节。应用结果表明,通道方式结构简单,传输稳定,安装调试环节减少,能够满足保护通道要求。In the traditional optical fiber multiplexing protection channel, the optical signal sent by the protection device needs to be converted into electrical signal by photoelectric conversion equipment and then multiplexed into SDH transmission. The opposite end also needs to convert the received electrical signal into optical signal and then send it to the protection device. In this way, the intermediate conversion link is added, resulting in low signal transmission efficiency, long delay and more hidden troubles. In order to solve the above problems, an optical fiber multiplexing protection channel based on 2 M optical interface was designed to eliminate the intermediate conversion link. The application results show that the channel is characterized by simple structure, stable transmission and less installation and debugging links, and can meet the requirements of protection channel.
