Abstract :
We demonstrated PM-64QAM, 20×124.8-Gb/s Nyquist-WDM over 1306 Km of PSCF in an EDFA-only submarine system configuration. The raw (net) SE was 10.4 (8.67) b/s/Hz, thanks to digital spectral shaping. The Tx DACs operated at a record-low 1.15 sample/symb thanks to advanced antialias filters. The SEDP was 11,327 (b.km)/(s.Hz), highest for PM-64QAM.
