Bidirectional WDM star single-hop networks with reusing wavelengths twice

摘要

摘要: 针对有限的数据信道波长数对波分复用星形单跳网容量的限制问题,文章提出了一种波长二次重用、单纤双向传输和多耦合器内连相结合的组网扩容解决方法.与常规波分复用星形网相比,该方法不但将网络所支持的节点数增加了两倍;而且网络的所有数据信道波长都得到二次重用,网络最大吞吐量也增加了两倍;在网络节点数不变的条件下,不但可节省一半的光纤,而且通过波长的二次重用,可大大减小网络中通信节点的排队时延,缓和各通信节点对数据信道波长使用权的竞争矛盾,有效地改善网络性能。

Abstract: For enlarging the capacities of WDM star networks free from the number of limited wavelengths, a scheme of reusing wavelengths twice is proposed in this paper. According to the scheme, not only the number of nodes can be increased twice, but also all the data wavelengths can be reused twice in the network and the throughput of the network is increased twice. Under the same number of nodes, not only half of fibers can be saved, but also the delay of network can be greatly lowered and the properties of the network can be efficiently improved.
