Electro-optically multiplexed 110 Gbit/s optical OFDM signal transmission over 80 km SMF without dispersion compensation

110 Gbit/s optical orthogonal frequency division multiplexing (OFDM) transmission is demonstrated over 80 km ITU-T G.652 singlemode fibre (SMF) without dispersion compensation. The optical OFDM signal is generated by a novel electro-optic subcarrier multiplexing technique that combines a two-carrier modulation scheme with an optical multi-carrier light source.
