提出了一种可靠的双光纤环树波分复用光接入网结构。一方面，由于采用差分相移键控调制，实现了包括点对点业务和广播业务在内的三播业务。另一方面，通过远程节点的特殊设计，可以动态分配波长。更重要的是，这种网络架构可以为单个或多个故障提供灵活的保护模式。网络的生存能力可以大大提高。
A reliable dual-fiber ring-tree wavelength-division multiplexing optical access network architecture is proposed in this paper. On the one hand, due to the use of differential phase shift keying modulation, triple-play service including point-to-point service and broadcast service is realized. On the other hand, the wavelengths can be allocated dynamically by means of the special design of the remote node. What is more important is this network architecture can provide flexible protection modes for either single or multiple failures as well. The network survivability could be improved largely.
