Abstract

This paper aims at looking beyond the gloomy current market evolution of the optical industry. Based on an analysis of the telecom transport market evolution (metropolitan as well as backbone), taking benefit of very significant technological breakthroughs in optics in recent years, this paper will suggest promising, yet pragmatic applications in telecom transport networks where optics will play a significant role beyond pure optical transmission.

Résumé

L’objectif de ce papier est de se placer au-delà de la sombre évolution du marché actuel de l’optique. Tirant bénéfice des ruptures technologiques dans ce domaine ces dernières années, cet article suggére des applications pragmatiques dans les réseaux de telecommunications de transport (aussi bien metropolitain que dorsal) où l’optique jouera un rôle significatif allant bien au dela de la simple transmission optique.
