Abstract

We investigated the performance of a 1.12-Tb/s (5×224-Gb/s PDM-16QAM) superchannel with 6-b/s/Hz, using optical prefiltering, over hybrid LongLine-SSMF link with hybrid Raman-EDFA amplification and cascaded 175-GHz ROADMs. A maximum reach of 1000-km with 10-ROADM passes was obtained employing nonlinear compensation.
