摘　　要：文章提出了一种基于数字信号的光传输环形网。当网络中的光纤线路出现故障时,网络能快速检测到故障线路,并在短时间内自动切换到保护通道,恢复网络通信。最后对该方案进行了测试验证,试验结果表明该方案是可行的。The paper presents a kind of ring network protection technology in special optical transport system base on digital signal.When any of the equipment or optical line in the network failed,the network could detect the failed line quickly,and switch to standby protection channel instantly to resume network communication.This design project was verifiable through experimentation,results of experimentation show that the design is feasible.

关 键 词：数字信号 光传输环形网 切换 保护
