DAC-Less and DSP-Free 20 Gb/s PAM-4 Transmission Based on a Dual Modulation Scheme Using DML and External Modulation (W6A.42)

Presenter: Laurent Bramerie, Institut FOTON

The generation of DAC-less 20 Gb/s PAM-4 using a DML and an external modulator is demonstrated. This dual modulation scheme has been transmitted up to 75 km SSMF with similar performance to PAM-4 DAC transmitter.
