Abstract :
By jointly using perturbation-based nonlinear pre-compensation and selective decision-aided perturbation-based nonlinear post-compensation, a reduction in the effective number of summation terms by a factor of about 4 is achieved for a 128 Gb/s dual polarization 16-ary quadrature amplitude modulation signal with essentially no degradation in performance. A transmission distance of 4800 km is achieved for a single channel system and a distance of 3000 km is achieved for the center channel in a nine-channel dense wavelength-division-multiplexing (DWDM) system with a channel spacing of 25 GHz.
