93% Complexity Reduction of Volterra Nonlinear Equalizer by ℓ1-Regularization for 112-Gbps PAM-4 850-nm VCSEL Optical Interconnect

We successfully transmit a 112-Gbps PAM-4 signal over 200-m OM4 fiber using 850-nm VCSEL and Volterra filter. Adopting ℓ1-regularization can reduce 93% of computation complexity of Volterra filter at the KP4 FEC limit.
