Abstract :
A 560 Gb/s (7×80 Gb/s Nyquist spaced PDM-16QAM) superchannel achieving 6.95 b/s/Hz spectral efficiency is transmitted over 253.4 km SMF-28® ULL fiber using only EDFA pre-amplification and full-field nonlinear back-propagation, corresponding to a record SE-distance product of 1761.1 b/s/Hz·km.
