  • Publication number: 20210003795
    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.

  • 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.
