We demonstrate a 56 GBd PAM-4 compact transmitter module integrating in InP a DFB laser and EAM modulator, which exhibits 50 GHz bandwidth, >13 dB extinction ratio and up to 1.5 mW output power. Successful amplifier free 2-km 112-Gb/s transmission is performed using low complexity 3 taps equalization. We also study the trade-off between receiver bandwidth, equalizer length and performance, showing that successfully signal recovery can be achieved with bandwidths as low as 18 GHz when increasing the equalizer length.
