我们通过实验证明了利用互补光谱反转光学相位共轭（CSI-OPC）可以同时缓解PDM-16QAM WDM信号的非线性。我们基于周期性极化的LiNbO3波导实现了保留无带、保护无带和极化无关的OPC。通过采用CSI-OPC，在保持WDM原始带宽的前提下，实现了2.325- thz （93 × 25 GHz）频段的互补频谱反演。在信号频带中心和信号频带边缘使用10通道WDM传输，确认了q2因子改善超过0.4 dB和q2因子高于FEC限制的5120公里传输。然后，我们演示了对所有92通道180 gbit /s PDM-16QAM准nyquist -WDM信号在3840公里长距离WDM信号传输中的非线性损伤的缓解。
We experimentally demonstrated the simultaneous nonlinearity mitigation of PDM-16QAM WDM signals using complementary-spectrally-inverted optical phase conjugation (CSI-OPC). We achieved reserved-band-less, guard-band-less, and polarization independent OPC based on periodically poled LiNbO3 waveguides. By employing the CSI-OPC, 2.325-THz-band (93 × 25 GHz) complementary spectral inversion was achieved while retaining the original WDM bandwidth. A Q2-factor improvement of over 0.4 dB and a 5120 km transmission with a Q2-factor above the FEC limit were confirmed using a 10-channel WDM transmission at the signal band center and signal band edge. We then demonstrated the mitigation of the nonlinear impairments in a 3840 km long-haul WDM signal transmission for all 92-channel 180-Gbit/s PDM-16QAM quasi-Nyquist-WDM signals.
