This work demonstrates a 56-Gbps 4-PAM EML-based transmission system. Using an O-band SIA to increase power budget and FFE/DFE to compensate SIA-induced ISM 37.8-km transmission is successfully implemented with BER below the FEC limit (2 x 10(-4)).

We successfully transmit a 112-Gbps PAM-4 signal over 200-m OM4 fiber using 850-nm VCSEL and Volterra filter. Adopting l(1)-regularization can reduce 93% of computation complexity of Volterra filter at the KP4 FEC limit.
