Theoretical and Simulation Approaches for Studying Compensation Strategies of Nonlinear Effects Digital Lightwave Links Using DWDM Technology

Nowadays, techniques for education are based on the combination of theoretical formulas, experimental measurement and simulation approaches. Theoretical analysis, experimental and simulation approaches based educations allow developing simple and non expensive tools for the aim of studying complex problems in optical network communication. Theoretical formulas, used to describe the non linear effects on digital lightwave links, may by simplified with the use of simulation models so that real and industrial applications can be approached. In this study, we use theoretical model taking into account system parameters, physical penalty and transmission speed, for the purpose of developing simulation tools. Using these simulation techniques, it is possible to investigate various compensation techniques and demonstrate their effects on system performances.
