We demonstrate simultaneous self-phase-modulation-based 2R regeneration of 2 x 10.65-Gb/s polarization-division-multiplexed (PDM) signals using a single section of highly nonlinear fiber (HNLF). Mitigation of inter-channel nonlinearities is achieved through a bidirectional configuration, rejecting of backward Stimulated Brillouin Scattering noise is obtained by signal re-polarizing before the offset filter and putting the center wavelength of filter at the short wavelength side of the signal. The power penalty improvement up to 2.0 dB for two PDM signals at 10(-9) BER is achieved.
我们展示了使用单段高非线性光纤（HNLF）对2×10.65 Gb/s偏振复用（PDM）信号进行基于自相位调制的同步2R再生。通过双向配置实现了通道间非线性的缓解，在偏置滤波器之前对信号进行重新偏振，并将滤波器的中心波长置于信号的短波长侧，从而抑制了反向受激布里渊散射噪声。对于误码率为10^(-9)的两个PDM信号，功率代价改善高达2.0 dB。
