Combining phase-sensitive amplifiers with DSP for enhanced nonlinearity mitigation
Paper in proceedings, 2019

We investigate combining phase-sensitive optical amplifiers (PSAs) with a static Volterra nonlinear equalizer (VNLE) to mitigate residual nonlinear distortions. Experiments show that the VNLE reduces penalties from link design and improves QBER by 0.4 dB for a 10-GBaud 16QAM signal in a 10×80-km PSA-amplified link.
