Summary:A fiber optic cable includes a core and a binder film surrounding the core. The core includes a central strength member and core elements, such as buffer tubes containing optical fibers, where the core elements are stranded around the central strength member in a pattern of stranding including reversals in lay direction of the core elements. The binder film is in radial tension around the core such that the binder film opposes outwardly transverse deflection of the core elements. Further, the binder film loads the core elements normally to the central strength member such that contact between the core elements and central strength member provides coupling there between, limiting axial migration of the core elements relative to the central strength member. Un câble de fibres optiques comprend un cœur et un film de liant entourant le cœur. Le cœur comprend un élément de renfort central et des éléments de cœur, tels des tubes tampons contenant des fibres optiques. Les éléments de cœur sont toronnés autour de l'élément de renfort central en un motif de toronnage contenant des inversions dans le sens du câblage des éléments de cœur. Le film de liant est en tension radiale autour du cœur d'une manière telle que le film de liant s'oppose vers l'extérieur à une déflexion transversale des éléments de cœur. De plus, le film de liant charge les éléments de cœur perpendiculairement à l'élément de renfort central d'une manière telle qu'un contact entre les éléments de cœur et l'élément de renfort central assure un couplage entre eux, ce qui limite une migration axiale des éléments de cœur par rapport à l'élément de renfort central.
