我们提出并演示了一种新的波分复用正交频分复用无源光网络（WDM-OFDM-PON）架构，该架构具有集中的光源和偏振移键控（PolSK）组播覆盖。实验验证了10gb /s 16QAM-OFDM点对点（P2P）信号、2.5 gb /s组播PolSK信号和2.5 gb /s开断键控（OOK）上行信号。在通过25km标准单模光纤（SMF）传输后，下游信号之间的1.5dB串扰通过在PolSK接收器上采用低通电滤波器消除。在误码率为10（-9）时，上行OOK信号的功率惩罚小于0.1dB。
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.
