Abstract

L'invention concerne un appareil de traitement de fibre optique qui comprend : un cadre (10) comportant une première extrémité et une seconde extrémité en regard l'une de l'autre dans le sens de sa longueur ; et un dispositif de coupe de fibre optique monté sur le cadre (10) pour couper une section nettoyée d'une fibre nue (1a) exposée à partir d'une fibre optique (1). L'appareil de traitement de fibre optique comprend en outre : un dispositif de dénudage de fibre monté sur le cadre (10) permettant de décoller une couche de revêtement sur la fibre optique (1) destinée à être traitée de manière à exposer la section de la fibre nue (1a) ; et un dispositif de nettoyage de fibre optique monté sur le cadre (10) pour nettoyer la section exposée de la fibre nue (1a). Étant donné que l'appareil de traitement de fibre optique dans son ensemble possède des fonctions intégrées de dénudage de la couche de revêtement de la fibre optique et de nettoyage et de coupe de la fibre optique, il peut par conséquent traiter la fibre optique de manière avantageuse, ce qui simplifie les procédures de traitement de la fibre optique avant continuation et améliore l'efficacité de traitement.
