  • Patent number: 9477057
    Abstract: A fiber optic cable includes a jacket, a pair of strength members, and an optical fiber. The jacket has a cavity, a major dimension and a minor dimension, and a medial portion. The strength members are disposed on opposing sides of the cavity and impart a preferential bend characteristic to the cable. The at least one optical fiber is disposed within the cavity. The jacket includes preferential tear portions disposed between a respective strength member and the medial portion, for separating the strength members from the medial portion.

  • Patent number: 9459422
    Abstract: A fiber optic cable includes a jacket forming a cavity therein, a stack of fiber optic ribbons located in the cavity, and a strength member embedded in the jacket. The jacket forms a ridge extending into the cavity lengthwise along the fiber optic cable. The ribbon stack is spiraled through the cavity such that corners of the ribbon stack pass by the ridge at intermittent locations along the length of the cable, where interactions between the ridge and the corners of the ribbon stack facilitate coupling of the ribbon stack to the jacket.

  • Publication number: 20160178864
    Abstract: Cables jacket are formed by extruding discontinuities in a main cable jacket portion. The discontinuities allow the jacket to be torn to provide access to the cable core. The discontinuities can be longitudinally extending strips of material in the cable jacket, and can be introduced into the extrudate material flow used to form the main portion through ports in the extrusion head. The discontinuities allow a section of the cable jacket to be pulled away from a remainder of the jacket using a relatively low peel force.

  • Publication number: 20160011392
    Abstract: Cables have dielectric armors with armor profiles that provide additional crush and impact resistance for the optical fibers and/or fiber optic assembly therein, while retaining flexibility to aid during installation. The armored cables recover substantially from deformation caused by crush loads.

  • Publication number: 20150355430
    Abstract: A fiber optic cable includes a core, armor surrounding the core, and a jacket surrounding the armor. The core includes tubes, each tube having a passage defined therein, optical fibers positioned in the passages, and a binder sleeve defining an exterior of the core. Portions of the binder sleeve are directly bonded to the armor, while other portions are not. Spacing between the armor and the core, as well as the bond between the armor and binder sleeve, facilitate tubing-off of an end section of the cable to include removal of the binder sleeve.

  • Patent number: 9140867
    Abstract: 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.

  • Patent number: 9091830
    Abstract: 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.
