Abstract

We propose a receiver-side digital nonlinear compensation (NLC) that solves a time-evolving equation for SOA-induced nonlinear distortion with SOA device parameters estimated by our ultra-broadband flexible-rate transmitter configuration. Experiments demonstrate that our SOA-NLC suppresses the SNR penalty by SOA for 168-GBaud signals to <0.29 dB.
