On statistical effects on stimulated Raman cross-talk

Abstract

We provide a statistical model that accounts for the effects of dispersion on stimulated Raman scattering cross-talk in wavelength division multiplexed systems with random initial binary data. When either the input power is not too large or the number of channels involved is moderate or the transmission distance is small, channels are found to follow a Binomial probability distribution that is the same for channels symmetric with respect to the middle one. This distribution can be approximated by a Gaussian when the number of channels is not too small. Our model works for any fibre dispersion or number of channels.

Impact of Channel Dynamics, Combined Nonlinearities and ASE Noise on Transmission Performance of all Optical Star WDM Networks

“…The two conventional limiting factors in the design of WDM systems, namely, fiber loss and dispersion, are relatively well understood, and can be easily overcome by optical amplifiers and dispersion compensation. The influence of fiber nonlinearities on the other hand, have not been fully analyzed and understood despite a rich collection of literature involving extensive studies deal- ing with the nonlinear effects on system performance [5][6][7][8][9][10][11][12]. Also, most investigations of nonlinear effects on WDM systems have primarily been done independently of each other i.e.…”
