一种新型IP OVER WDM城域网的节点结构

摘要

A new node architecture for a wavelengt h division multiple (WDM) packet-switched metropolitan area network based on su b carrier multiplexed addressing and wavelength conversion technology is proposed. The network operates on dual-bus topology and the tunable transmitter and fixed receiver s c heme to facilitate data multiaccess. Subcarrier multiplexed addressing and wavel ength conversion based on cascaded semiconductor optical amplifier perform the f unctions of subcarrier signal with data multiplexing and transparent transmissio n of payload.%提出了一种基于波分复用(WDM)、分组交换、副载波复用和波长变换技术的新型全光 城域网节点结构。网络拓扑采用环形，网络节点采用可调输出固定输入的选波原则以利于数 据的多重接入。副载波复用和基于级联半导体光放大器的波长变换，实现了射频副载波路由 信息与基带IP数据包的同步复用和IP数据包的透明传输。
