摘　　要：本文提出了一种分群式波分复用网，该网络用户端配一个固定频率的接收机（ＦＲ，ＦｉｘｅｄＲｅｃｅｉｖｅｒ）和一个调谐范围十分有限的发送机（ＴＴ，ＴｕｎａｂｌｅＴｒａｎｓｍｉｔｔｅｒ），网络的最大跳数等于２。本文利用系统性通道配置算法，使每个ＴＴ的调谐范围最小同时获得最小的平均跳数。本文提出的波分复用网对可调光器件要求低，能支持大量用户。分析和数值结果表明在均匀业务分布时，网络中各用户群的单跳概率相等，网络的基本性能如平均跳数、最大吞吐量等都几乎只与通道数目有关，而与用户数无关。A cluster-based WDM network is proposed in this paper, where each user is equipped with afix tuned receiver and a limited tunalbe transmitter.The network achieves constant maximum hop of 2. It adoptsa systematic channel assignment algorithm ( CAA) to minimize the tuning range of each transmitter meanwhileminimizing the average hop. Analysis and mumerical results show that the network obtains equivalent single hopprobability among clusters under the uniform traffic . Furthermore,its basic performance such as average hop andmaximum throughput , is almost only related with wavelength number, having little to do with the user number.
