摘　　要：采用光分路器级联光纤延迟线作为波分复用星形网的光接收机缓存可以提高网络的性能。光纤延迟线的个数影响网络的性能,它们之间级联的方式影响整个网络的性价比。对网络性能模拟的结果表明当光纤延迟线的个数增加到一定数量之后再继续增加,网络性能的提高很小。在此基础上,提出了一种新的光纤延迟线级联结构,这种结构具有无源、可模块化、高可靠性和高性价比的突出优点。The performance of a WDM star network based on reservation MAC protocols can be improved by using optical fiber delay-lines （FDLs） as optical buffers at the receivers. With the number of FDLs increasing, the performance of the network improves. By using discrete event simulation technology ,it is proved that when the number of FDLs is larger than 5 the incremental improvement of the network becomes negligible. This scheme has the peculiarities of passive, modularization and cost effictive.
