摘要

首先介绍了现在流行的实现动态可重新配置光上下路复用器（ROADM）模块的解决方案

然后提出了一种简化的ROADM模块和网络结构

接着探讨了它在传送网络升级改造中可能的应用。该方案可用于提高新老设备的利用率

解决峰值时间和各站点间通信堵塞问题。文章还提出了一种用简化的ROADM实现环间业务动态调度的方法。文章所建议的ROADM模块具有成本低、对网络中其它信号干扰小等优点。

Abstract

The paper describes popular ways to realize the dynamic ROADM （reconfigurable optical add/drop multiplexing） module at first. Then a simplify ROADM module and network architecture is proposed

and the possible applications in transmission networks are discussed. This solution can improve the equipments utilization factor

partly solving the problems of the peak time communications block （jam） among nodes. This paper also provides a way to realize the dynamic traffic re-arrangement between rings. The ROADM module suggested here has advantages of low cost and low interfere with other signals in the same networks.
