Prototype de validation de la couche physique d'un réseau optique sans filtre

Abstract

The recent technological developments allow many new optical network architectures possibilities. The electronic dispersion compensation, the use of tunable transmitters and tunable receivers constitute determinant technological progresses in the development of filterless optical networks. In fact, filterless optical networks appear now as a valuable solution to the growing needs of a more simple and flexible network architecture, as the traffic increase. Filterless optical networks are based on the use of tunable transmitters and receivers and of a minimum number of active elements for the optical commutation or network configuration. Filterless optical networks are also characterized by the use of power splitters as optical fiber interconnection elements and as multiplexing and demultiplexing elements. In this master' s thesis, an analytical methodology whose purpose is the physical constraints validation of a filterless optical network is presented. This analytical model is validated with the simulation software VPitansmissionMaker ™. Finally, according to the analytical model presented, a physicallayer validation prototype for filterless optical network is proposed. Developed in the MATLAB® environment, it is based on the noise's level management and prediction, mainly caused by optical amplifiers in a filterless optical network. This prototype is an efficient way to evaluate the physicallayer of filterless optical networks. Because of the quick calculation time and the process' simplicity, this tool becomes a major asset in the generation and evaluation of filterless optical network solutions.
