We propose and demonstrate a novel wavelength-division-multiplexing orthogonal-frequency-division-multiplexing passive-optical-network (WDM-OFDM-PON) architecture with centralized lightwave sources and polarization shift keying (PolSK) multicast overlay. The 10-Gb/s 16QAM-OFDM point to point (P2P) signal, 2.5-Gb/s multicast PolSK signal and 2.5-Gb/s on-off keying (OOK) upstream signal are experimentally demonstrated. After transmission over 25km standard single mode fiber (SMF), 1.5dB crosstalk between the downstream signals is eliminated by employing a low pass electrical filter at the PolSK receiver. The power penalty of the upstream OOK signal at BER of 10(-9) is less than 0.1dB.
我们提出并演示了一种新颖的波分复用正交频分复用无源光网络（WDM-OFDM-PON）架构，该架构采用集中式光波源和偏振移位键控（PolSK）多播叠加。实验演示了10 Gb/s 16QAM-OFDM点对点（P2P）信号、2.5 Gb/s多播PolSK信号和2.5 Gb/s开关键控（OOK）上行信号。在25公里标准单模光纤（SMF）上传输后，通过在PolSK接收器处采用低通电滤波器消除了下游信号之间1.5 dB的串扰。在误码率为10^(-9)时，上行OOK信号的功率代价小于0.1 dB。
