Publication number: 20240118509Abstract: 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.Type: ApplicationFiled: December 18, 2023Publication date: April 11, 2024Inventors: Bradley Jerome Blazer, Rodney Maurice Burns, James Garrett Dewell, Julian Latelle Greenwood, III, Keith Aaron Greer, Warren Welborn McAlpine

Patent number: 10598882Abstract: 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.Type: GrantFiled: February 28, 2019Date of Patent: March 24, 2020Assignee: Corning Optical Communications LLCInventors: Gregory Blake Bohler, Julian Latelle Greenwood, III, Keith Aaron Greer, Wesley Brian Nicholson, Kimberly Dawn Slan

Publication number: 20190049686Abstract: 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.Type: ApplicationFiled: October 15, 2018Publication date: February 14, 2019Inventors: Jeffery Alan Clampitt, Julian Latelle Greenwood, Leigh Rooker Josey, Warren Welborn McAlpine, Eric John Mo:!dy, Jorge Roberto Serrano
