Query: Deep Neural Network Assisted Second-Order Perturbation-Based
  Nonlinearity Compensation   We propose a fiber nonlinearity post-compensation technique using the DNN and
the second-order perturbation theory. We achieve 1 dB Q-factor improvement for
a 32 Gbaud PDM-64-QAM at 1200 km compared to the linear dispersion
compensation.
