An optical fiber cable (20) includes a longitudinally extending copper core member (34). The core member is formed with at least one groove (36) in which is disposed at least one optical fiber. The optical fiber is coupled sufficiently to the core member preferably by an ultraviolet light energy cured material to substantially inhibit relative movement between the optical fiber and the core member when forces are applied to the cable. A sheath system which includes a plastic jacket (112) is disposed about the core member. The sheath system includes a strength member system which includes longitudinally extending copper wires (105, 105) and steel wires (101, 107). Disposed about the steel and copper wires is a steel shield (110) which provides hermetic protection for the optical fibers. A waterblocking material (108) is disposed among the wires and between an inner layer of the wires and the core member to cooperate with the compressive engagement of the inner layer of strength members with the core member to couple the strength members to the core member.
âble à fibres optiques (20) muni d'un jonc de cuivre (34) qui se déploie longitudinalement. Ce jonc présente au moins une rainure (36) où est placée au moins une fibre optique. On utilise un matériau traité au rayonnement ultraviolet qui rattache assez fermement cette fibre optique au jonc pour empêcher tout mouvement sensible de la fibre optique par rapport au jonc lorsque le câble subit l'action de forces s'exerçant sur lui. Un système de gainage comportant notamment une enveloppe de plastique (112) entoure le jonc. Ce système de gainage comprend un système d'armure fait notamment de fils de cuivre (105, 105) et de fils d'acier (101, 107) disposés longitudinalement. Autour de ces fils d'acier et de cuivre est disposé un blindage en acier (110) qui offre une protection hermétique aux fibres optiques. Un matériau étanche (108) est placé entre les fils et entre une couche interne des fils et le jonc, afin de contribuer, avec la fixation de la couche interne de l'armure au jonc, à rattacher solidement l'armure au jonc.
