An optical fiber cable (20) includes a longitudinally extending core member (34) which may be made of a plastic material. The core member is formed with at least one groove (36) in which is disposed at least one optical fiber (28). The optical fiber is coupled sufficiently to the core member, preferably by an ultraviolet light energy cured material, to inhibit substantially relative movement between the core member and the optical fiber when forces are applied to the cable. A sheath system which includes wire-like strength members and a plastic jacket (112) is disposed about the core member. A waterblocking material (108) disposed within interstices among the wire-like strength members and between an inner layer of the strength members and the core member causes coupling between the wire-like strength members and the core member.
Un câble à fibre optique (20) comporte un coeur longitudinal (34) qui peut être fabriqué en matière plastique. Le coeur longitudinal comporte au moins une rainure (36) à l'intérieur de laquelle au moins une fibre optique (28) est insérée. La fibre optique est couplée au coeur longitudinal, de préférence à l'aide d'un matériau polymérisé par lumière ultraviolette, afin d'inhiber tout mouvement relatif entre le coeur et la fibre optique sous l'effet des forces exercées sur le câble. Un système de gainage utilisant des éléments de renforcement de type filamenteux et un chemisage en plastique (112) entoure le coeur longitudinal. Un matériau hydrofuge (108) disposé dans les interstices entre les éléments de renforcement de type filamenteux et entre la surface intérieure de la couche de renforcement et le coeur longitudinal assure la liaison entre les éléments de renforcement et le coeur longitudinal.
