We demonstrate the generation of a novel 1.2-Tb/s NGI-CO-OFDM superchannel comprising of 24 frequency-locked 12.5-GHz spaced PDM-QPSK carriers, and transmit it over 72×100-km of ultra-large-area fiber, achieving 3.7-b/s/Hz channel spectral-efficiency (SE) and a record SE-distance product of 27,000-km·b/s/Hz.
