Title
(EN) OPTICAL FIBER CABLE WITH LASER WELDED JACKET AND METHOD OF MANUFACTURING
(FR) CÂBLE À FIBRES OPTIQUES À GAINE SOUDÉE ET PROCÉDÉ DE FABRICATION
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. 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 laser welding 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 présentant une surface interne définissant un canal à l'intérieur de la gaine de câble. Le câble comprend une ligne de fusion à l'intérieur de la gaine de câble qui associe les bords longitudinaux opposés d'une feuille thermoplastique enroulée qui forme la gaine de câble et maintient la gaine de câble 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 de noyau optique. Le procédé consiste à faire fondre ensemble des parties de matériau thermoplastique de bords longitudinaux opposés de la feuille enroulée de telle sorte qu'une ligne de fusion est formée maintenant la feuille de matériau thermoplastique enroulée autour des éléments de noyau.
