Phys. Rev. Lett. 91, 203901 (2003) [4 pages]Information Capacity of Optical Fiber Channels with Zero Average DispersionReceived 14 March 2003; published 13 November 2003 We study the statistics of optical data transmission in a noisy nonlinear fiber channel with a weak dispersion management and zero average dispersion. Applying analytical expressions for the output probability density functions both for a nonlinear channel and for a linear channel with additive and multiplicative noise we calculate in a closed form a lower bound estimate on the Shannon capacity for an arbitrary signal-to-noise ratio. © 2003 The American Physical Society URL:
