Popis: 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 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 with the well-known digital back propagation (DBP) algorithm for a wavelength division multiplexed system consisting of eight dual-polarization 16QAM channels operating at 28 GBd transmitted through a $15\times 100$ km 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.
