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.

Key words: TWDM, PON, PolSK, orthogonal modulation technology
