我们提出了一种新的方案，在波分复用无源光网络（WDM-PON）上覆盖多播数据与点对点的数据传输。差分相移键控多播信号被叠加到所有点到点不归零（NRZ）信号上。通过调整各个NRZ点对点信号的消光比，可以实现多播，并且只有指定的光网络单元可以正确地接收多播数据。我们成功地展示了所提出的WDM-PON与10 Gb/s的下行点对点信号和10 Gb/s的组播信号。
We propose a novel scheme to overlay multicast data on a wavelength-division-multiplexed passive optical network (WDM-PON) with point-to-point data delivery. The differential phase-shift keying multicast signal is superimposed onto all point-to-point nonreturn-to-zero (NRZ) signals. By adjusting the extinction ratios of the individual NRZ point-to-point signals, multicast can be realized and only the designated optical network units can properly receive the multicast data. We successfully demonstrated the proposed WDM-PON with 10-Gb/s downstream point-to-point signals and 10-Gb/s multicast signals.
