Abstract

In the context of long-haul Nyquist wavelength division multiplexed (WDM) superchannel system, a fifth-order Volterra-based nonlinear equalizer (VNLE) is proposed to compensate for the optical fiber nonlinear effects, which represent the major fiber impairment in such high data rate systems. A performance comparison of the fifth-order VNLE with the benchmark digital-back propagation (DBP) and the third-order VNLE is provided. We show that the fifth-order VNLE better combats the fiber nonlinearity in comparison with the third-order VLNE and exhibits closer performance to the DBP. A significant improvement of the performance in terms of the Q factor, nonlinear threshold, and transmission reach is observed when compared with the third-order VNLE.
