随着40Gbit/s端口路由器的出现及传输业务带宽迅速增长的需求,基于40Gbit/s传输速率的波分系统将被逐步广泛使用。本文根据中国移动80×40Gbit/s试商用工程设计中的具体情况,分析探讨40Gbit/s的关键技术及对现有维护运行体系的影响。
With the advent of 40Gbit / s port routers and the rapid growth of transmission service bandwidth, the WDM system based on 40Gbit / s transmission rate will be widely used gradually. This text analyzes and discusses the key technology of 40Gbit / s and influence on the existing maintenance and operation system according to the concrete conditions of China Mobile’s 80 × 40Gbit / s pilot commercial engineering design.
