BINDER FILM SYSTEM

摘要

A fiber optic cable includes core elements wound in a pattern of stranding, the core elements comprising tubes surrounding optical fibers. The fiber optic cable further includes an binder film surrounding the stranded core elements. The binder film is continuous peripherally around the core elements, forming a continuous closed loop when viewed in cross-section, and continuous lengthwise along a length of the cable that is at least a meter. Further, the binder film is in radial tension and opposes outwardly transverse deflection of the core elements.

1. A fiber optic cable, comprising:
inner core elements wound in a pattern of stranding, the inner core elements comprising tubes surrounding optical fibers; an inner binder film surrounding the stranded inner core elements, wherein the inner binder film is continuous peripherally around the core elements, forming a continuous closed loop when viewed in cross-section, and continuous lengthwise along a length of the cable that is at least a meter, and wherein the inner binder film is in radial tension and opposes outwardly transverse deflection of the inner core elements; and outer core elements wound in a pattern of stranding around the inner binder film and the inner core elements, the outer core elements also comprising tubes surrounding optical fibers.
