Experimental demonstration of 1600 km SSMF transmission of a generalized direct detection optical virtual SSB-OFDM system
We experimentally demonstrate a generalized VSSB-OFDM format that judiciously determines the frequency gap between an inserted RF tone and the signal. The proposed scheme for 10 Gbps exhibits ~3 dB penalty after 1600 km SSMF transmission, and has an 8 dB improvement over the regular VSSB-OFDM.
