Abstract :
We present an analytical solution for intra-channel nonlinearity based on perturbation theory. By relaxing the unrealistic lossless assumption in the conventional method, the model accuracy is improved by 20% for 1500km CD-managed link. Further application of the model shows a 0.6dB Q improvement under a 128Gb/s DP-QPSK pre-distortion experiment.
