非线性相位噪声，通常称为戈登-莫伦诺尔效应，可以通过从接收相位中减去与接收强度成比例的校正来电子补偿。通过解析推导出最优比例因子，近似等于平均非线性相位噪声与平均接收强度之比的一半。通过最优补偿，残差相位噪声的标准差减半，使受非线性相位噪声限制的系统的传输距离增加一倍。
Nonlinear phase noise, often called the Gordon-Mollenauer effect, can be compensated electronically by subtracting from the received phase a correction proportional to the received intensity. The optimal scaling factor is derived analytically and found to be approximately equal to half of the ratio of mean nonlinear phase noise and the mean received intensity. Using optimal compensation, the standard deviation of residual phase noise is halved, doubling the transmission distance in systems limited by nonlinear phase noise.
