本文提出了一种新型共轭驱动频移键控（FSK）调制波分复用无源网络（WDM-PON），具有可变速率多播服务。对于不同速率要求的组播覆盖业务，采用光正交频分复用(OFDM)。采用差分检波对FSK信号进行解调，可以消除OFDM信号的串扰。通过实验演示了总共 40 Gb/s FSK 点对点 (P2P) 信号和 6.3 Gb/s OFDM 与三种可变速率多播服务的叠加。针对可变速率组播服务提出了物理层自适应识别。经过 25 km 单模光纤 (SMF) 传输后，FSK P2P 信号和 OFDM 组播覆盖的功率损失分别为 1.3 dB 和 1.7 dB。
This paper proposes a novel conjugate-driven frequency shift keying (FSK) modulated wavelength division multiplexing passive network (WDM-PON) with variable-rate multicast services. Optical orthogonal frequency division multiplexing (OFDM) is adopted for multicast overlay services with different rate requirements. A differential detection is used for the demodulation of FSK signal, which can eliminate the crosstalk from the OFDM signal. A total 40-Gb/s FSK point to point (P2P) signal and 6.3-Gb/s OFDM overlay with three kinds of variable-rate multicast services are experimentally demonstrated. A physical-layer adaptive identification is proposed for the variable-rate multicast services. After 25 km single mode fiber (SMF) transmission, the power penalties of FSK P2P signal and OFDM multicast overlay are 1.3 dB and 1.7 dB respectively.
