We transmit a 1.5-Tb/s guard-banded superchannel, consisting of eight 30-Gbaud pilot-free PDM-OFDM-16QAM signals spaced at 32.8 GHz, over 52 100-km ultra-large-area fiber spans, achieving the highest spectral-efficiency-distance product of 29,892 km⋅b/s/Hz for Tb/s-class superchannel transmission with >5 b/s/Hz net spectral efficiency.
