Numerical Analysis of Dispersion Compensation Schemes for Pseudo-linear Transmission System

Abstract

AbstractA pseudo-linear optical transmission system analytical model is built for the numerical analysis of dispersion compensation schemes. The system performance under the influence of intra-channel nonlinear effects and the initial pulse power is discussed for the data rates of 10, 40, 100 and 160 Gbit/s, respectively. We get the conclusion for the first time as we know the optimal dispersion compensation scheme for the optimal system performance is closely related to the system data rate and the proportion of the pre-dispersion compensation should be decreased while that of the post-dispersion compensation be increased with the increasing of system data rate. When the system data rate is higher than 160 Gbit/s, we can use the post-dispersion compensation scheme directly.
