Abstract

L'invention concerne un procédé et un appareil permettant d'amplifier un signal optique. Un premier filtre sépare un signal optique en une première et une deuxième partie. Un premier amplificateur Raman amplifie la première partie. Un deuxième amplificateur à constantes localisées amplifie la deuxième partie. Un combinateur combine les première et deuxième parties amplifiées.
