基于波长选择开关的混合WDM/TDM PON结构

Wavelength selected switches-based hybrid WDM/TDM PON architectures

介绍了混合WDM/TDM PON的一般网络结构,重点探讨基于波长选择开关的部分灵活的混合PON结构,包括具有固定组播功能的混合PON、无组播功能的混合PON和具有选择组播功能的PON结构形式和功能优缺点,为波分时分复用混合无源光网络的具体设计提供参考。

In this paper,a general hybrid WDM/TDM PON architecture is introduced.And some new partially flexible hybrid WDM/TDM PON architectures using wavelength selective switches （WSSs） at the remote node are discussed expressly,including partially flexible architectures with fixed multicasting,partially flexible architectures without multicasting,and partially flexible architectures with selective multicasting.And these new architectures can provide a useful reference to build a hybrid optical access network for future.
