通过引入分布式结构+反馈回路+波长分组的方法，提出了一种新的波长三次重用的多波长星形光网络。这种新的网络通过多耦合器内连和网络所有信道波长的三次重用，使网络规模和网络最大吞吐量都达到常规WDM星形网的4倍；通过单纤双向传输，在网络节点数相同的条件下，可节省光纤50%；通过采用分布式结构，使网络的抗毁性得到大幅度提高。

In this paper, a novel multi-wavelength star optical network reusing all channel wavelengths three times is proposed by the method of “（Distributed Architecture) + (Return Link) + (Wavelength Group)”. In this scheme, by interconnecting four conventional star couplers and reusing all channel wavelengths three times, both the maximum number of supportable nodes and the maximum throughput of the network are all up to four times as many as that of conventional WDM star network. Utilizing bidirectional transmissions in a single fiber, half fibers can be saved under the same number of supportable nodes. Making use of the distributed architecture, the anti-destructibility of network is drastically raised. All these advantages of the network efficiently overcome the disadvantages of conventional WDM star network.
