A low-cost 4×25Gbps PAM4 module for short-reach optical interconnection

A low-cost 4×25Gbps PAM4 module for short-reach optical interconnection has been proposed using the commercial low-cost 10Gbps DML TOSA and PIN ROSA. This scheme has been demonstrated over 2km SMF and can also be used for MMF interconnection.
