A detachable plug-in pump laser card assembly (14) for placement into an optical fiber amplifier, comprising: a printed circuit board (16), a heat sink (20), a pump laser (18), an optical connector first half plug-in member (22), an electrical connector second half plug-in member (24), and a reel (26) having an optical fiber (28) wrapped therearound. The heat sink is substantially parallel to the printed circuit board and is separated therefrom by spacers (42). The pump laser is connected to one side of the heat sink, which has a plurality of fins (40) on an opposite side. The first half plug-in member and the second half plug-in member are each located at an insertion end of the pump laser card assembly. The optical fiber wrapped around the reel has a first end connected to the pump laser and a second end connected to the first half plug-in member.

L'invention concerne un ensemble carte laser de pompage enfichable et démontable (14), s'insérant dans un amplificateur à fibres optiques et comprenant : une carte de circuit imprimé (16), un dissipateur thermique (20), un laser de pompage (18), un premier bloc de connexion optique de l'élément enfichable (22), un second bloc de connexion électrique de l'élément enfichable (24), et un tambour (26) autour duquel est enroulée une fibre optique (28). Le dissipateur thermique est sensiblement parallèle à la carte de circuit imprimé, de laquelle il est séparé à l'aide de cales de séparation (42). Le laser de pompage est relié à une face du dissipateur thermique, l'autre face étant pourvue d'ailettes (40). Les premier et second blocs de l'élément enfichable sont situés chacun à une extrémité d'insertion de l'ensemble carte laser de pompage. La fibre optique enroulée autour du tambour comporte une première extrémité reliée au laser de pompage et une seconde extrémité reliée à la première moitié de l'élément enfichable.
