Abstract

On a mis au point un appareil et un procédé d'augmentation de la plage de mesure optique dans des réflectomètres optiques à domaine temps, utilisant un amplificateur à laser à fibres pour amplifier les impulsions du réflectométre optique à domaine temps, lancées dans un guide d'ondes. L'appareil et le procédé présentent une utilité particulière pour des réseaux locaux ramifiés. Le signal revenant dans le réflectomètre optique à domaine temps est amplifié, ainsi que le signal de limite extérieure.
