Inhalt:
We investigate the performance of a Volterra-based nonlinear equalizer and the digital backpropagation (DBP) method in multi-channel nonlinear equalization after 20×80 km transmission distance. The Volterra equalizer, which operates with single-step-per-span, performs similarly compared to DBP with 40 steps-per-span.
