对4× 12 Gbaud-16 QAM波分复用信号进行了非线性补偿实验，得到了大于10 dB的非线性阈值改善，其中对称功率演化是必不可少的。我们还数值研究了不同4×67.25Gbaud-16 QAM WDM传输距离的Q2惩罚与功率对称性。
Nearly perfect nonlinear compensation of 4× 12Gbaud-16QAM WDM signals is experimentally demonstrated to achieve nonlinear threshold improvement greater than 10dB, in which symmetric power evolution is essential. We also numerically investigate Q2-penalty versus power symmetry for varying 4×67.25Gbaud-16QAM WDM transmission distances.
