Title
(EN) CABLE HAVING AN AT LEAST PARTIALLY OXIDIZED ARMOR LAYER AND METHOD AND APPARATUS FOR MAKING SAME
(FR) CABLE A ARMURE AU MOINS PARTIELLEMENT OXYDEE, PROCEDE ET DISPOSITIF POUR SA FABRICATION
Abstract
(EN)
A coaxial, fiber optic, or twisted pair cable having a core surrounded by an armor layer and an outer protective jacket is provided wherein relative movement between the armor layer and the protective jacket is permitted. The armor layer has a pair of opposing longitudinal edge portions and is wrapped around a cable core such that a longitudinally extending seam is produced. The outer surface of the armor layer has an adhesive layer disposed thereon for bonding an outer protective jacket thereto. Portions of the outer surface of the armor layer adjacent the longitudinally extending seam are oxidized, thereby effectively neutralizing the adhesive layer. The oxidized portions of the armor layer reduce, if not eliminate, adherence between the protective jacket and the armor layer along the longitudinally extending seam.
(FR)
L'invention concerne un câble à fibres optiques à paire coaxiale ou torsadée dont l'âme est enveloppée dans une armure et une gaine extérieure de protection, avec un mouvement relatif entre l'armure et la gaine de protection. L'armure a une paire de bordures longitudinales opposées et enserre l'âme du câble de manière à former un bourrelet longitudinal. La surface externe de l'armure a une couche adhésive à laquelle adhère la gaine extérieure de protection. Certaines parties de la surface externe de l'armure, en position adjacente au bourrelet longitudinal, sont oxydées, ce qui neutralise efficacement la couche adhésive. Les parties oxydées de l'armure ont la capacité d'éliminer, et en tout cas de réduire, l'adhérence entre la gaine de protection et l'armure, le long du bourrelet longitudinal.
