摘要
本文对本地WDM网络节点上波分复用设备的配置进行了分析 ,认为在城域WDM网中一般只配前置放大器 ,而大本地网需在收端配前置放大器 ,发端配功率放大器 ,对于节点距离超过100km的情况下 。
Node configurations of WDM equipment in local network has been analyzed. It is suggested that only preamplifiers are needed in city area network , while both preamplifiers and postamplifier are needed in big local network. When the distance between nodes is beyond 100 km , line amplifiers are necessary.
