Piecewise linear equalizer for 56 GBit/s PAM-4 signal transmission using DML with large adiabatic chirp

Computationally efficient piecewise linear (PWL) equalizer is, for the first time, proposed to compensate amplitude-dependent skews caused by DML chirp and chromatic dispersion. 56 Gbit/s PAM-4 signals in C-band are respectively enabled for 40 km and 60 km transmission below the HD-FEC and SD-FEC.
