Transmission impairments and their mitigations,Digital signal processing algorithms for optical communications

We show that addition-multiplication (AM)-model is closest to nonlinear fiber channel among the 1st-order perturbation models and the reverse MA-model is the best pre-distortion and post-compensation method because of equivalence to propagating an inverse fiber.
