Abstract

L'invention concerne un système de communication optique (200) et un appareil d'amplification à bande divisée (212) qui amplifie des signaux optiques dont la bande courte de longueur d'onde comprend au moins une partie de la bande S et dont la bande longue de longueur d'onde comprend au moins une partie de la bande C et/ou de la bande L. Ledit appareil d'amplification (212) présente une première (212A) et une deuxième (212B) section permettant d'amplifier respectivement les bandes de longueur d'onde longues et courtes. La deuxième section (212B) comprend une fibre passe-court (10) présentant un noyau (12) dopé avec un matériau actif (18) de type erbium. Une source de pompe pompe l'erbium à un niveau d'inversion D relative élevé de façon que l'erbium présente des gains positifs dans la bande S et des gains élevés dans une bande longue de longueur d'onde plus longue que la bande S, c'est-à-dire dans les bandes C et L. Ledit noyau (12) est entouré par une gaine déprimée (14) elle-même entourée par une deuxième gaine (16). Ledit noyau (12) présente une section transversale et un indice de réfraction no, la gaine déprimée (14) présente une section transversale de gaine déprimée et un indice de réfraction n1, et la gaine secondaire (16) présente une section transversale de gaine secondaire et un indice de réfraction n2. La section transversale de noyau, la section transversale de gaine déprimée et les indices de réfraction n0, n1, et n2 sont sélectionnés afin d'obtenir des pertes au moins comparables aux gains élevés dans la bande longue de longueur d'onde et des pertes sensiblement inférieures aux gains positifs dans la bande S. L'amplificateur à fibre fonctionne en tant que préamplificateur, qu'amplificateur dynamiseur de puissance ou qu'amplificateur en ligne dans ledit système de communication optique.
