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.

Armored optical fiber cable

An optical communication cable includes a jacket, optical transmission elements, and armor. The jacket is mostly formed from a first material and includes an elongate member formed from a second material embedded in the first material. The jacket defines a channel in which the optical transmission elements are located. The armor includes a wrapped sheet having a lateral edge and is positioned around the optical transmission elements within the channel. The elongate member has an inner surface aligned with and located exterior to the lateral edge of the armor; and, when viewed in cross-section, the elongate member fully overlays and extends tangentially beyond the lateral edge. Accordingly, the elongate member provides an obstacle in the jacket that limits zippering through the jacket originating from the lateral edge. Further, the elongate member may double as a tear feature for quickly accessing contents of the cable interior to the jacket.

Optical fiber cable with anti-split feature

An optical communication cable includes a core, armor surrounding the core, a jacket surrounding and bonded to the armor, and a binder film also surrounding the core and interior to the armor. The core includes buffer tubes surrounding sets of optical fibers and a central strength member. The buffer tubes are stranded around the central strength member in a pattern of stranding including reversals in lay direction of the buffer tubes and the binder film holds the buffer tubes in position. The binder film is bonded to an interior of the armor, thereby providing a quick access capability to access the core via simultaneous removal of the binder film when the armor and jacket are removed.
