An investigation was carried out on the polarization attraction (PA) of a polarization-scrambled 10.7-GBaud NRZ-BPSK signal in a 1-km-long highly nonlinear fiber (HNLF). For the back-to-back case, PA on an ASE-loaded signal yielded a receiver sensitivity penalty of ≈ 14.5 dB at the ITU-T G.975.1.I3 FEC threshold of 3.5 × 10, relative to matched-filter reception theory. After long-haul 100-GHz DWDM transmission in a recirculating loop, PA on the output signal was found to achieve approximately the same receiver sensitivity performance, as that of the back-to-back case. From these experiments, it is concluded that the Gordon-Mollenauer effect due to propagation in the HNLF during PA dominates other impairments including those arising from the long-haul 100-GHz DWDM recirculating loop transmission.
对1公里长的高非线性光纤（HNLF）中偏振扰码的10.7 GBaud NRZ-BPSK信号的偏振吸引（PA）进行了研究。对于背对背情况，相对于匹配滤波器接收理论，在ITU-T G.975.1.I3 FEC阈值为3.5×10时，ASE加载信号上的PA导致接收器灵敏度损失约14.5 dB。在循环环路中进行长距离100 GHz DWDM传输后，发现输出信号上的PA实现了与背对背情况大致相同的接收器灵敏度性能。从这些实验可以得出结论，在PA期间在HNLF中传播引起的戈登-莫勒纳尔效应主导了其他损伤，包括那些由长距离100 GHz DWDM循环环路传输引起的损伤。
