Abstract

We show that co-optimization of dispersion and power maps in long-haul fiber optic communications can significantly mitigate the effects of group-velocity dispersion (GVD) and self phase modulation (SPM). A genetic algorithm is used for arriving at the optimal (or a near-optimal) link design in reasonable time, since exhaustive search is almost impossible for this intractable problem. Design of a 20-span×80 km/span link that can recover an input Gaussian pulse almost in its original form is presented. This design provides near-optimum values of the required net dispersion, dispersion map, and power map to mitigate the effects of SPM and GVD
