Resumo: This article presents a new strategy to search for satisfactory wavelengths assignments in an optical link considering the Four Wave Mixing (FWM) effect in optical fibers. The FWM effect is taken into account for the calculation of the fiber Noise Figure for each wavelength. In this work we analyze the assignments when there are additions and droppings of wavelengths, considering the best and satisfactory assignments by using exhaustive and genetic algorithms (GA), respectively. A new crossover operator for the GA utilized was developed and tested. With this approach the distributions of wavelengths are obtained from modified one genetic algorithm, which considers the quality of service criterion based on Bit Error Rate. We show that our new crossover operator outperforms the previous one presented in the literature.
