Real Time 100 Gbit/s/λ PAM-4 Experiments for Future Access Networks over 20 km with 29 dB Optical Budget

Abstract

We achieve 29 dB of optical budget and 20 km reach in a 50 Gbaud PAM-4 experiment at pre-FEC BER threshold of 10−2. A PDFA at OLT, a SOA-PIN at ONU are used in a real time experiment.
