1Tb/s (111Gb/s/ch × 10ch) no-guard-interval CO-OFDM transmission over 2100 km DSF

We demonstrated spectrally efficient (2-b/s/Hz) 1Tb/s DWDM transmission of 111 Gb/s no-guard-interval PDM CO-OFDM signals over DSFs with 50 GHz spacing. The record transmission distance of 2100 km in the 100-Gb/s-data-rate CO-OFDM systems was achieved.
