Title
(EN) LASER WELDING OF CABLE JACKET
(FR) SOUDAGE LASER DE GAINE DE CÂBLE
Abstract
(EN)
An optical cable and method for forming an optical cable is provided. The cable includes a cable jacket including an inner surface defining a channel and an outer surface and also includes a plurality of optical fibers located within the channel. The cable includes a seam within the cable jacket that couples together opposing longitudinal edges of a wrapped thermoplastic sheet which forms the cable jacket and maintains the cable jacket in the wrapped configuration around the plurality of optical fibers. The method includes forming an outer cable jacket by wrapping a sheet of thermoplastic material around a plurality of optical core elements. The method includes melting together portions of thermoplastic material of opposing longitudinal edges of the wrapped sheet such that a seam is formed holding the sheet of thermoplastic material in the wrapped configuration around the core elements.

L'invention concerne un câble optique et un procédé de formation d'un câble optique. Le câble comprend une gaine de câble comprenant une surface interne définissant un canal et une surface externe, ainsi qu'une pluralité de fibres optiques situées à l'intérieur du canal. Le câble comprend un joint à l'intérieur de la gaine de câble qui couple ensemble les bords longitudinaux opposés d'une feuille thermoplastique enroulée qui forme la gaine de câble, et maintient la gaine de câble dans la configuration enroulée autour de la pluralité de fibres optiques. Le procédé consiste à former une gaine de câble externe en enroulant une feuille de matériau thermoplastique autour d'une pluralité d'éléments d'âme optique. Le procédé consiste à faire fondre ensemble des parties de matériau thermoplastique des bords longitudinaux opposés de la feuille enroulée de telle sorte qu'un joint est formé maintenant la feuille de matériau thermoplastique dans la configuration enroulée autour des éléments d'âme.
