Investigating dispersion and nonlinearity interaction in optical fibers for hybrid optical telecommunication systems

The effect of interaction between fiber dispersion and nonlinearities in DWDM hybrid optical communication system is investigated. Eight DWDM wavelengths, 100-GHz spaced chosen on ITU-grid were used in the study. Different hybrid configurations of 10 Gbps and 40 Gbps signals were considered. Numerical simulations were conducted to predict the performance of each signal transmitted. Bit-error-rate criterion was used to quantify the performance of each signal. Optimal regimes of operation were found for different hybrid configurations.
