摘要:

提出一种基于TWDM-PON系统的改造方案。其实现方案是在其原有的4个基于ASK调制的通信波长上附加一个单独的基于PolSK调制的通信信道,并使用这个信道传输组播数据,使ONU能够实现
在单个波长上同时接收单播和组播业务。这种改造方案可以提高TWDM-PON系统的组播业务传输效率,提升系统整体的性价比。

Abstract:

A new method based on TWDM-PON system is proposed in this paper. Based on its original four communication wavelengths based on ASK modulation, a separate PolSK
modulation based communication channel is added. The channel can be used to transmit multicast data, enabling the ONU to achieve receiving unicast and multicast services in a
single wavelength. The transmission efficiency and performance of TWDM-PON system can be improved by using this kind of method.
