Etude des réseaux optiques translucides : évaluation de leur faisabilité technique et de leur intérêt économique

Abstract : The arrival and mastery of new optical transmission technologies and all-optical switching of signals in optical networks allow the introduction of transparency in the core network. In transparent networks, optical signals are not converted to electronic signals except when added or dropped. A translucent transport network is half way between an opaque network (systematic opto-electrical conversion at each node) and a transparent network. This type of network provides a trade-off between transparency and opacity and permits: · Alleviate the need for opto-electrical devices without restricting either the length of connexions in the network or the wavelength constraint, assuring a balance between signal performance at reception and total network cost. · Operation of the network independent of certain signal characteristics (bit rate, modulation, etc) making the network more adaptive to developments. These aspects make this type of network very attractive for providers, such as France Télécom. The goal of this thesis is to determine network feasibility and the advantages that could be brought to the backbone network. This study is original in the use of physical constraints linked to network dimensioning; these features are the main research axes of the present work.
