摘　　要：针对现有分布反射型 WDM星形单跳网结构上存在的问题 ,本文提出了一种新的分布反射型 WDM星形单跳网 .这种 WDM网络不仅抗毁性能好、可靠性高 ,而且网络容量大、组网灵活性强 ,可实现网络的在线扩容、升级 ,为未来大容量 WDM局域网提供了一个理想的选择 .文章首先论述了该分布反射型大容量 WDM星形单跳网的结构 ,其次分析了网络中各个节点之间的通信 ,进而计算了网络所支持的最大节点数 。To overcome the disadvantages of the structure of distributed reflective WDM star single hop networks,a new distributed reflective large scale WDM star single hop network is proposed in this paper.Not only the network has better reliability,much larger capacities of network and better flexibility of networking,but also its capacities can be expanded on line.So,it provides a good selection for large scale WDM local area networks in future.At first,the structure of the network is introduced.Next,communications among nodes in the network are analyzed.Moreover,the maximum number of nodes supported by the network is computed.Finally,a conclusion about the network is given.
