摘　　要：为了满足下一代光接入网对于数据传输越来越高的要求,文章提出了一种新颖的波分复用光接入网架构。通过全新设计的远端节点及光信号放大与组合模块,该网络不仅可以提供信号长距离传输与广播业务,同时还具有灵活的可扩展性以及光纤共享保护功能。这些特点使得网络具有良好的弹性,能抑制信号传输过程中产生的瑞丽后向散射噪声,并可以实现整个网络对于上行信号的光源进行共享。仿真结果显示网络具有良好的传输性能。In order to meet the higher requirements of the next generation optical access network for data transmission, a novel WDM optical access network architecture is proposed in this paper. Through the new design of remote node and optical signal amplification and combination module, the network can not only provide long distance transmission and broadcast service, but also have flexible scalability and optical fiber sharing protection function. These features make the network with good flexibility. Additional, it retains the merits of Rayleigh backscatter mitigation and shared-seeding light of upstream signals. Simulation results show＂ that the network has good transmission pertbrmance.
