Optical Transmission Cable Patents (Class 385/100)
  • Patent number: 10382838
    Abstract: Example management closures (110) enable incoming optical and/or electrical signals to be connected to one or more subscribers (109) via an electrical distribution cable (102). Termination connections within the management closure (110) are connected to active electronic equipment (131) for modifying and/or enhancing the incoming signals. However, the connections between the central office (101), the active electronic equipment (131), and a subscriber (109) need not be made until the subscriber requests a service upgrade. Accordingly, the closure (110) allows for simple and low cost installation of the closure (110) before upgraded service is needed.

  • Patent number: 10353156
    Abstract: Multi-fiber, fiber optic cable assemblies may be configured so that the terminal ends of the cables have pre-assembled back-post assemblies that include pre-assembled ferrules, such as MPO ferrules that meet the requisite tolerances needed for fiber optic transmissions. To protect the pre-assembled components from damage prior to and during installation, pre-assembled components may be enclosed within a protective housing. The housing with pre-assembled components may be of a size smaller than fully assembled connectors so as to be sized to fit through a conduit. The remaining connector housing components for the multi-fiber connectors may be provided separately and may be configured to be attached to the back-post assembly after installation of the cable.

    Abstract: An optical cable includes an optical core and an external sheath surrounding the optical core. The external sheath includes a first material having a first, higher fracture toughness and a second material having a second, lower fracture toughness. The first and second materials are arranged so that the second, lower fracture toughness material is accessible from outside the cable along at least one longitudinally extending area of the sheath outer surface. For accessing the optical core of the cable, a short longitudinal cut, namely, few centimeters, is made with a blade in the accessible second, lower fracture toughness material. Then, its cut edges are pulled apart by hand. The pulling force causes the lower fracture toughness material to fracture, thereby propagating the initial short cut longitudinally along the sheath through its whole thickness.

  • Patent number: 9995899
    Abstract: An optical fiber distribution or breakout cable for serving multiple customer premises in a multi-dwelling unit (MDU) building. The cable contains a number of bend insensitive fibers each having a different colored coating for identification. A jacket of a flame-retardant polymer compound is extruded to surround the fibers. The jacket is sufficiently opaque to hide the color coated fibers at least partially from view, and the outer diameter of the jacket is not more than about 3.5 mm. A procedure for installing the cable through a hallway of a MDU building so as to lessen any negative visual impact of the installation on observers nearby is also disclosed.

  • Patent number: 9939590
    Abstract: A self-cleaning optical fiber connector system for ensuring dust or contaminants are cleared from an optical connection interface is disclosed. In one aspect, the optical fiber connector system includes a connector joining first and second connectors. The adapter has a main body defining a central opening within which the connectors are received. The connectors each include a fiber optic cable secured by a ferrule. In one aspect, the ferrule defines an airflow passageway that narrows between a second opening and a first opening proximate an end face of the cable optical core and cladding. The connectors are constructed such that, as each connector is being inserted into the connector, an air flow is generated through the ferrule airflow passageway, and optionally through an exhaust airflow passageway in the connector. The generated airflow clears debris from the exposed end faces. Electrostatic precipitation may also be used to aid in clearing dust and debris, alone or in combination with air flow effects.

  • Patent number: 9915792
    Abstract: Fiber optic cable demarcations inhibiting movements of optical fibers relative to strength members, and related cable assemblies and methods, are disclosed. By bonding optical fibers to strength members with a bonding agent received into at least one cavity, a demarcation may be formed inside the cable jacket at a cable jacket interface. The at least one cavity may be disposed within a cable jacket of a fiber optic cable and at the cable jacket interface. The demarcation may bond at least one optical fiber and at least one strength member together to inhibit longitudinal movement of the at least one optical fiber relative to the at least one strength member. In this manner, the demarcation may inhibit optical fiber movement within the fiber optic connector, which may cause tensile forces and/or buckling of the optical fiber resulting in optical fiber damage and/or optical attenuation.
