Etude et optimisation d'une chaîne de transmission numérique par voie optique : vers une compensation électronique des effets de la PMD

Abstract : The evolution of optical fibre transmissions accelerated these last years. The need to transmit high bit rates (today equal to or higher than 40 Gb/s) over increasingly large lengths of transmission is constantly growing. Unfortunately, the sensitivity of propagation to defects increases with the bit rate. These effects are related to chromatic dispersion CD, polarization mode dispersion PMD, or to nonlinear effects primarily induced by the effect Kerr (dependence of the index of refraction of fibre of the light intensity). In this context, this work focuses on the study of the effects of CD and the PMD on the optical transmissions. Moreover, the PMD is identified today as the principal source of limitation in high bit rate transmissions. In addition to that, birefringence in optical fibres represents the principal cause of PMD. In this work, we particularly focused on the study of the effects of the temperature on the PMD in monomode standards fibres (SMF) corresponding to specification ITU-G.652 used in the optical networks. By taking into account of the ellipticity of the fibre, the variation of the PMD according to the temperature is studied through the evolution of birefringence according to the parameter V of fibre for various temperatures. This work of thesis opens the way to develop an architecture making it possible to compensate for the PMD by digital signal processing. The main idea is to replace an expensive technology (optical components) by a numerical architecture at low cost, and more universal. The works in progress on the compensation of the PMD by electronic way are encouraging and seem very promising at short-term
