256 GBd single-carrier transmission over 100km SSMF by a plasmonic IQ modulator

A plasmonic IQ modulator is used to demonstrate 160 GBd 64QAM with achievable data-rates of 774 Gbit/s in a single-carrier back-to-back experiment. Over a 100 km fibre link it achieves 256 GBd 4QAM and 160 GBd 16QAM with rates of 410 and 600 Gbit/s.
