Abstract
A coaxial, fiber optic, or twisted pair cable having a is core surrounded by an armor layer and an outer protective jacket such that 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.
