Abstract

Employing time-domain hybrid QAM, training-assisted phase recovery and cascaded equalization, we successfully transmitted ten 494.85Gbit/s PDM-32/64QAM DWDM signals at 8.25b/s/Hz net spectral efficiency (SE) over 40⨉100km, achieving a record terrestrial SEdistance product of 33,000- kmb/s/Hz.
