Wavelength Assignment Considering Four Wave Mixing Using Genetic Algorithm

Abstract

This article presents a new estrategy to assign wavelengths in a optical link considering the four wave mixing effect in the optical fiber. The four wave mixing effect in taken into account by using a formulation that calculates the fiber noise figure for each wavelenght. We analyze the assignments when there are additions and droppings of wavelengths, considering the best and satisfactory assignments using the exhaustive and genetic algorithms, respectively. We obtain the distributions o wavelengthms from a genetic algorithm, which considers the quality of service criterion based on bit error rate. We show that our strategy is capable of determining assignments of wavelength, the maximum number of wavelengths and their positions in the grid to minimize the impact of the four wave mixing effect.
