Abstract

A multicast scheme in WDM-PON is realized by superimposing multicast DPSK signal onto downstream point-to-point Manchester/NRZ signal. The proposed system is experimentally demonstrated with 5-Gb/s point-to-point Manchester/NRZ format signal and 1.25-Gb/s DPSK signal. At the receiver side, a MZDI and a LPF are employed to retrieve the multicast DPSK signal.
