我们目前的实验和数值研究克尔非线性补偿在400公里的标准单模光纤链路与分布式拉曼放大与后向泵浦。采用双泵浦偏振无关光纤光参量放大器实现了5 × 28-GBd偏振复用16-QAM信号的中间链路频谱反转。在单信道和五信道波分复用（WDM）系统的情况下，分别获得了1.1 dB和0.8 dB的信号质量因子（Q因子）的改善。实验结果进行了比较，数值模拟具有良好的一致性。它还示出了与模拟的最大传输范围为2400公里的光相位共轭器启用的WDM信号是可能的。
We present experimental and numerical investigations of Kerr nonlinearity compensation in a 400-km standard single-mode fiber link with distributed Raman amplification with backward pumping. A dual-pump polarization-independent fiber-based optical parametric amplifier is used for mid-link spectral inversion of 5 × 28-GBd polarization-multiplexed 16-QAM signals. Signal quality factor (Q-factor) improvements of 1.1 dB and 0.8 dB were obtained in the cases of a single-channel and a five-channel wavelength-division multiplexing (WDM) system, respectively. The experimental results are compared to numerical simulations with good agreement. It is also shown with simulations that a maximum transmission reach of 2400 km enabled by the optical phase conjugator is possible for the WDM signal.
