摘要 总结了光传送网生存性目前采用的基本技术,分析了1+1、1:1、1:n、m:n四种光层保护模式,特别对环形网和网状网结构的光层保护进行了研究。最后结合工作/保护光通道功率测试、故障定位、开光倒换协调等技术,设计了一个符合我国光通信发展现状的1:1光层保护方案。 First, the technical research situation of ONT survivability is given ,Second several optical layer protection modes (1+1, 1.1, 1 :n, m:n)were summarized, The protection schemes of ring systems and mesh architectures were expressly analyzed, Lastly a 1:1 protection scheme that fitted to our country is designed, It is based on combining technology of working/protection channels optical power monitoring, fault location, switching coordination and so on.
