Abstract

It is experimentally shown that employing multi-staged reverse self-phase-modulation in a coherent receiver compensates for waveform distortion due to self-phase-modulation including the inter-polarisation nonlinearity of polarisation-division multiplexing and inter-subcarrier nonlinearity of orthogonal frequency division multiplexing. This scheme extends the transmission distance 1.25-fold under an uncompensated dispersion map to suppress cross-phase-modulation, and a 10-channel times111 Gbit/s OFDM signal is successfully transmitted 12times015 km at the spectrum efficiency of 2.0 bit/s/Hz with a 1.0timesdB penalty reduction.
