Adaptive Digital Compensation of Cascaded SOA Nonlinearities in Metro-Access Networks Without Prior Parameter Knowledge
We propose a systematic data-aided scheme that adaptively post-compensates for cascaded SOA-induced nonlinear distortions by tuning unknown SOA parameters. Nonlinear post-compensation demonstrates a 3-dB sensitivity improvement in 20-Gbaud PAM-4 experiments, enabling a symbol rate higher than 50 Gbaud after three-cascaded SOA transmission in simulations.
