16.2-Tb/s field trial over 2,531-km of installed SSMF with DP-QPSK optical superchannels

We report 16.2-Tb/s transmission over 32×79.1-km spans of field fiber using optical superchannels with DP-QPSK modulated subcarriers. The achieved capacity-distance product of 40.9-Pb/s-km is the highest reported to date for a field trial.
