[Orientations des recherches sur les systèmes de transmission terrestres]
La technique du multiplexage en longueur d'onde a permis l'émergence de débits multi-Terabit/s dans les réseaux optiques terrestres. Récemment, nous avons réalisé en laboratoire une transmission en environnement terrestre de données à 6.3 Tbit/s sur la distance record de 2700 km. Après avoir décrit les particularités des transmissions optiques terrestres, nous détaillons les différentes technologies qui peuvent être utilisées pour atteindre un tel objectif, à savoir le format de modulation, la configuration des amplificateurs optiques, l'électronique à 40 Gbit/s et les codes correcteurs d'erreurs.
The technique of wavelength division multiplexing (WDM) has paved the way for multi-terabit/s capacities in terrestrial optical networks. Recently, we conducted a laboratory experiment to emulate a terrestrial transmission of 6.3 Tbit/s capacity over a record 2700 km distance. After describing some of the specific features of optical terrestrial transmission, we discuss the various technologies possibly involved in such an emulator and discuss their implementation in actual systems, namely the modulation format, the optical amplifier scheme, the 40 Gbit/s electronics and the forward error-correcting codes.
