Armored optical fiber cable

摘要

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.

1. An optical communication cable, comprising:
(A) a core of the cable, comprising:
(i) optical fibers each comprising a core surrounded by a cladding;(ii) buffer tubes surrounding subsets of the optical fibers,(iii) a central strength member, wherein the buffer tubes are stranded around the central strength member in a pattern of stranding including reversals in lay direction of the buffer tubes; (B) armor surrounding the core of the cable, wherein the armor comprises metal; (C) a jacket surrounding and bonded to the armor, wherein the jacket comprises a polymer; (D) a binder film to hold the buffer tubes in position around the central strength member,
wherein the binder film surrounds the core of the cable and is interior to the armor, wherein the binder film is bonded to an interior of the armor, thereby providing quick access to the core of the cable via simultaneous removal of the binder film when the armor and jacket are removed; and (E) water-absorbing powder particles positioned on an interior surface of the binder film, between the binder film and the core of the cable.
