    "abstract": "We consider the communication channel given by a fiber optical transmission\nline. We develop a method to perturbatively calculate the information capacity\nof a nonlinear channel, given the corresponding evolution equation. Using this\ntechnique, we compute the decrease of the channel capacity to the leading order\nin the perturbative parameter for fiber optics communication systems.",
