Computation of power penalties due to intraband crosstalk in optical systems

Error probabilities and power penalties produced by crosstalk are theoretically investigated. Expressions for the computation of the error probabilities using Gaussian and non-Gaussian models are presented. Experimental results for the one and two crosstalk cases are shown and compared to the theoretical computer-calculated results. The power penalties predicted by the Gaussian and non-Gaussian models are compared and the results are discussed.
