摘要
针对光纤通信系统中克尔非线性效应引起的信号畸变,对非线性频域内信号的预补偿方案进行了研究。在理想条件以及非理想条件(附加损耗,ASE噪声)下,预补偿处理后的信号都能较好地缓解非线性效应。
In order to mitigate kerr nonlinear effect in optical fiber commtmication system, a method based on nonlinear frequency domain is studied. Whether the transmission link with or without loss and ASE noise, the nonlinear effect can be alleviated effectively by the precompensated method.
