ROADM技术及其实现的研究(本期优秀论文)

Study on technology and implementation of ROADM

随着ROADM技术的发展,运营商逐渐采用它作为传送网的重要光节点。文章分析了当前ROADM的三种主要技术(分别基于波长阻塞器、集成平面光波导和波长选择开关),讨论了实现ROADM的几个方案,提出一种称为Semi-ROADM的节点结构。它能在利用新技术的同时,降低成本、有效保护投资。

With the development of ROADM technologies, carriers gradually adopt ROADM as important optical nodes in their transport network. This paper analyzed three kinds of present ROADM which are based on WB,iPLC and WSS respectively, discussed several schemes to implement ROADM, then puts forward a new architecture of optical node that is named Semi ROADM. Semi-ROADM can reduce the high cost and effectively protect carriers＇ investment when taking advantage of new technologies.
