20.8 Tb/s Transmission over 1200 km Using G654E Fibers, Hybrid Amplification and 400 Gb/s CFP2-DCO Interfaces

By using a 400 Gb/s 64Gbaud CFP2-DCO interface, we show error free transmission on fifty-two 75 GHz-spaced spectral positions of a fully loaded 4800 GHz-wide WDM comb over 1200km of G654E fiber with hybrid amplification.
