    "abstract": "We study the statistics of optical data transmission in a noisy nonlinear\nfiber channel with a weak dispersion management and zero average dispersion.\nApplying path integral methods we have found exactly the probability density\nfunctions of channel output both for a non-linear noisy channel and for a\nlinear channel with additive and multiplicative noise. We have obtained\nanalytically a lower bound estimate for the Shannon capacity of considered\nnonlinear fiber channel.",
