A method of preparing an optical fiber for fusion splicing comprising the steps of providing an optical fiber having a fiber jacket and an end, removing a predetermined bulk of the fiber jacket from an area adjacent the end while one of substantially simultaneously moving gas over the area and exhausting gas from the area in order to clean the optical fiber. Preferably the fiber jacket is removed by cutting with laser beam. The fiber end is ablated to create a smooth surface normal to the fiber's longitudinal axis.

L'invention porte sur un procédé de préparation de fibres optiques en vue d'un épissage par fusion consistant à se procurer une fibre optique munie d'une gaine et présentant une extrémité, et à éliminer une quantité prédéterminée de la gaine dans une zone voisine de l'extrémité, puis en y faisant entrer et ressortir quasi simultanément un gaz de manière à nettoyer la fibre optique. La gaine de la fibre sera de préférence éliminée par sectionnement au rayon laser. La fibre subit ensuite une ablation pour créer une surface lisse normale à son axe longitudinal.
