Abstract
We report the detection of a record 606-Gb/s data rate (503-Gb/s excluding 20.5%-FEC-overhead) by a single coherent receiver using four 80-Gsamples/s 32.5-GHz-bandwidth ADCs and reduced-guard-interval CO-OFDM with 32-QAM. Transmission of the signal with 7.76-b/s/Hz net intrachannel spectral efficiency is demonstrated.
