ÉTUDE D'UN SYSTÈME BAS COÛT DE TRANSMISSION OPTIQUE PAR MULTIPLEXAGE TEMPOREL

Abstract : The aim of this thesis is to develop a low-cost 10 Gb/s optical time division multiplexing system (OTDM). The required optical pulse train for the system has been generated by external modulation of an optical source continues, with an intensity modulator. Simulations demonstrated the feasibility of the studied system. A theoretical study solved the problem of interferences due to the coherent nature of the used source. The performances of the experimental multiplexing system were compared for two different optical sources. The demultiplexing is made with an electroabsorption modulator (EAM). Values of Bit Error Rate (BER), below 10-10, have been achieved experimentally, for each extracted channel. The designed system is compatible the wavelength division multiplexing (WDM) technology.
