Abstract
An optical communication cable subassembly includes a cable core having optical fibers each comprising a core surrounded by a cladding, buffer tubes surrounding subsets of the optical fibers, and a binder film surrounding the buffer tubes. Armor surrounds the cable core, the binder film is bonded to an interior of the armor, and water-absorbing powder particles are provided on an interior surface of the binder film.
Claims3
An optical communication cable comprising:
- a jacket formed from an extruded first material and including an inner surface defining a channel;
- a plurality of optical transmission elements located within the channel;
- a binder film surrounding the plurality of optical transmission elements to define a continuous closed loop when viewed in a cross-section perpendicular to a long axis of the cable, wherein the binder film is continuous lengthwise for at least 10 meters along a length of the cable, and wherein a thickness of the binder film is less than a fifth of a thickness of the jacket;
- and
- an armor layer located within the channel surrounding the binder film, wherein the armor layer includes a first lateral edge and an opposing second lateral edge and the armor layer is wrapped around the plurality of optical transmission elements and the binder film such that the first lateral edge overlaps the second lateral edge creating an overlap portion, and wherein the binder film is bonded to an inner surface of the armor layer and an outer surface of the armor layer is bonded to the inner surface of the jacket.
