  • Publication number: 20240118509
    Abstract: A fiber optic cable includes a cable core of core elements and a protective sheath surrounding the core elements, an armor surrounding the cable core, the armor comprising a single overlap portion when the fiber optic cable is viewed in cross-section, and a jacket surrounding the armor, the jacket having at least two longitudinal discontinuities extruded therein. A method of accessing the cable core without the use of ripcords includes removing a portion of the armor in an access section by pulling the armor away from the cable core so that an overlap portion separates around the cable core as it is being pulled past the cable core. A protective sheath protects the core elements as the armor is being pulled around the cable core.

  • Publication number: 20230418012
    Abstract: An optical fiber cable including a central strength member, a first plurality of tight-buffered ribbon stacks, a binder film, and a cable sheath. The central strength member extends along a longitudinal axis of the optical fiber cable. The tight-buffered ribbon stacks are SZ-stranded around the central strength member. An interstitial space is provided between adjacent tight-buffered ribbon stacks. A binder film continuously and contiguously surrounds the first plurality of tight-buffered ribbon stacks along the longitudinal axis. The binder film includes first portions and at least one second portion. Each of the at least one second portion of the binder film extends into one of the interstitial spaces of the first plurality of tight-buffered ribbon stacks. The cable sheath continuously and contiguously surrounds the binder film along the longitudinal axis, and the cable sheath is coupled to the first portions of the binder film.

  • Patent number: 10598882
    Abstract: Cables have dielectric armor with an armor profile that resembles conventional metal armored cable. The armor can be formed as a single layer, without requiring an outer jacket layer. The dielectric armor provides additional crush and impact resistance for the optical fibers and/or fiber optic assembly therein. The armored cables recover substantially from deformation caused by crush loads. Additionally, the armored fiber optic assemblies can have any suitable flame and/or smoke rating for meeting the requirements of the intended space. The assemblies can additionally be lightweight and relatively inexpensive to manufacture.

  • Publication number: 20190049686
    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.
