Transmission of 1.2 Tb/s continuous waveband PDM-OFDM-FDM signal with spectral efficiency of 3.3 bit/s/Hz over 400 km of SSMF
22 March 2009
We demonstrate generation, transmission and reception of a 1.21 Tb/s continuous waveband PDM-OFDM-FDM signal with spectral efficiency of 3.33 bit/s/Hz. After DCF-free transmission over 400-km SSMF a considerable Q-factor margin of 2 dB vs. EFEC limit was achieved.
