An optical wavelength division multiplexing metro access network is proposed in this paper. With the design of flexible distribution node (FDN), three kinds of reconfigurable networks can be flexibly built to achieve intra- and inter-optical network unit (ONU)-direct communications. With the adoption of multiple tangent twin-ring topologies, four-level shared protections covering both feeder and distribution fibers are also supported. Moreover, the network can be smoothly expanded by adding express ONUs connected to FDNs. Thus, the network can not only achieve capacity increasing but also support full-duplex reconfigurable communication. A reconfigurable transmission algorithm is also set to avoid wavelengths conflict.

支持三层重配置和四重共享保护的双环光WDM-MAN

本文提出了一种光波分复用城域接入网。通过灵活分配节点(FDN)的设计,可以灵活地构建三种可重新配置的网络,以实现内部和内部光网络单元(ONU)的直接通信。通过采用多个正切双环拓扑,还支持覆盖馈线和分配光纤的四级共享保护。此外,可以通过添加连接到FDN的快速ONU来平滑扩展网络。因此,网络不仅可以实现容量增加,还可以支持全双工可重配置通信。还设置了可重新配置的传输算法,以避免波长冲突。
