  • Patent number: 8737787
    Abstract: Cables are constructed with discontinuities in the cable jacket that 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. 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.
    Type: Grant

  • Patent number: 8724947
    Abstract: Cables have armor including a polymer, the armor having an armor profile that resembles conventional metal armored cable. The 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.

  • Publication number: 20140099062
    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: 20140086543
    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. Further, the binder film loads the core elements normally to the central strength member such that contact between the core elements and central strength member provides coupling therebetween, limiting axial migration of the core elements relative to the central strength member.

  • Publication number: 20130236148
    Abstract: An armored fiber optic cable includes fiber optic assembly, including at least one optical fiber, and dielectric armor in the form of an extruded polymeric tube surrounding the fiber optic assembly. The dielectric armor has at least one layer formed from a rigid material having a Shore D hardness of about 65 or greater. Further, the dielectric armor has an armor profile such that the dielectric armor has an undulating surface along its length.

  • Publication number: 20130058614
    Abstract: Discrete bands (60) are applied to switchback regions (50) of stranded cable cores (10) to secure the stranded tubes (20) prior to jacketing. The bands (60) obviate the need for complex processes such as the application of binder threads.

  • Patent number: 7941021
    Abstract: The present disclosure is generally directed to a fiber optic distribution cable assembly having an interior portion and an exterior portion. A distribution cable includes a plurality of optical fibers disposed within the interior portion and at least one predetermined mid-span access location positioned along a length of the distribution cable to provide access from the exterior portion to the interior portion. At least one optical fiber of the distribution cable is accessed and terminated from the distribution cable within the interior portion of the distribution cable. A tether having a first end is attached to the distribution cable through the mid-span access location. The tether has at least one optical fiber optically connected to the at least one terminated optical fiber of the distribution cable at a location within the interior portion of the distribution cable.

  • Publication number: 20080193092
    Abstract: Disclosed are fiber optic cables having a cable jacket or buffer tube with a cavity. Disposed within the cavity are at least one optical fiber and a coupling agent. The coupling agent acts to couple the at least one optical fiber to the cable jacket or buffer tube with a predetermined force, but the coupling agent does not substantially fill a cross-section area of the cavity, thereby providing a nearly “dry” fiber optic cable. Additionally, the fiber optic cable can optionally include one or more water-swellable components for blocking the migration of water within the cavity. Variations include fiber optic cables having the desired flame-retardant ratings for indoor use, outdoor cables with adequate water-blocking, and/or cables suitable for indoor/outdoor use.

  • Patent number: 7397992
    Abstract: Disclosed are tubeless fiber optic cables having strength members, methods of making the cables, and methods for making strength members. Specifically, the concepts of the invention inhibit the distortion and/or influence the cross-sectional shape of the tubeless fiber optic cables due to torsional forces from the strength members. For instance, one tubeless fiber optic cable of the invention uses strength members with a dead-lay construction for inhibiting distortion of the same. Another tubeless fiber optic cable design uses strength members on opposite sides of the cavity where the torsional forces from the strength members are in opposite directions for influencing the cross-sectional shape of the same. Other aspects of the invention are directed to methods for making the tubeless fiber optic cables.
