摘要
文章提出了一种基于密集波分复用器(DWDM)和光分插复用器(OADM)、以物理拓扑为总线型、逻辑拓扑为星形的适合于铁路通信各站光接入的光传输网方案,描述了光节点结构及这种网络的波长重复利用和自愈保护功能,实验测试了逻辑单星形光网络的传输特性,分析了网络规模的限制因素.
We have proposed an optical access scheme for railway communication stations based on physical bus and logical star DWDM-OADM architecture optical transport networks. The OADM optical nodes architecture was described, the logical dual-star architecture's self-healing function was illustrated. We have demonstrated the logical single-star architecture network transmission performance and analysed the factors limiting the network scale.
