We propose an optoelectronic method for the distributed compensation of nonlinear fiber distortions affecting polarization multiplexed signals. This method involves placing devices we call total-intensity-directed phase modulators (TID-PMs) at the start of each amplified fiber span, in order to compensate the effect of fiber nonlinearity on a span-by-span basis. Numerical simulations are used to compare our proposed method to the wellknown digital back propagation (DBP) algorithm for a wavelength division multiplexed (WDM) system consisting of eight dualpolarization 16QAM (DP-16QAM) channels operating at 28 Gbaud transmitted through a 15×100km dispersion unmanaged link. These simulations show that the proposed distributed nonlinearity compensation technique increases the peak signal quality, Q, by 1 dB while DBP only increases peak Q by 0.5 dB
