  • Patent number: 9176293
    Abstract: Buffered optical fibers are formed by extruding discontinuities in the buffer layer. The discontinuities allow the buffer layer to be torn to provide access to the buffered optical fiber. The discontinuities can be longitudinally extending strips of material in the buffer layer, and can be introduced into the extrudate material flow used to form the first section of the buffer layer in the extrusion head.

  • Patent number: 9170389
    Abstract: Hybrid fiber optic cables including one or more electrical coaxial subassembly allowing for fiber movement to reduce attenuation during bending are disclosed. Related connectorized cables and systems are also disclosed. The hybrid fiber optic cables include both one or more coaxial subassembly and optical fibers to provide both optical and electrical connectivity as part of a connectorized system. Use of one or more coaxial subassembly reduces impedance variations and lowers cost. Each coaxial sub-assembly also includes multiple electrical conductors to increase electrical connectivity capacity (e.g., power and signals) of the hybrid cable, as needed or desired. Further, the hybrid cable may include a channel with optical fiber(s) of the hybrid cable disposed therein, free of attachment to the channel. The channel allows the optical fibers to move relative to the cable jacket and control bend radius to reduce optical attenuation when the hybrid fiber optic cable is bent.

  • Patent number: 9151895
    Abstract: Thermal removal of optical fiber coatings by insertion through heated ferrules to form ferrule assemblies for fiber optic connectors, and related assemblies are disclosed. An optical fiber includes a glass fiber, having a cladding and core, surrounded by a protective coating. By removing the coating at an end portion of the optical fiber, the end portion may be precisely positioned and secured within a ferrule to enable reliable optical communications. The coating may be thermally removed, or substantially thermally removed, by inserting the optical fiber through a rear opening of the ferrule which has been heated above a temperature sufficient to change the coating to a non-solid state. In this manner, the coating may be efficiently removed from the end portion of the optical fiber while being inserted into the ferrule bore of the ferrule to enable efficient forming of a ferrule assembly for a fiber optic connector.

  • Patent number: 9148960
    Abstract: Embodiments disclosed herein include receiver optical assemblies (ROAs) having a photo-detector remotely located from a differential transimpedance amplifier (TIA). Related components, circuits, and methods are also disclosed. By providing the photo-detector remotely located from a TIA, additional costs associated with design constraints of providing the photo-detector intimate with a TIA may be avoided, thereby reducing cost of the ROA. In this regard as a non-limiting example, the ROAs according to the embodiments disclosed herein allow shorter haul active optical cable applications for use in consumer applications from a cost standpoint with the added benefits of increased bandwidth and low noise performance of optical fiber.

  • Patent number: 9089931
    Abstract: Systems and methods for laser cleaving optical fibers are disclosed. In certain embodiments discussed herein, a ferrule of a fiber optic connector with an optical fiber disposed therein may precisely position an optical surface of the optical fiber when establishing an optical connection with another optical fiber. The optical surface may be thermally formed by laser beam(s) directed to an end face of the ferrule and to an end portion of the optical fiber extending therefrom. By having at least ninety (90) percent of the light incident on the ferrule as S-polarized light, the optical surface may be formed closer to the ferrule. This is because the laser beam may be more readily reflected away from the ferrule instead of being absorbed within the ferrule and thereby causing ferrule damage.

  • Patent number: 9091829
    Abstract: Disclosed are optical connections having a coupling portion that includes a piston and a magnet along with complimentary optical connections. In one embodiment, the optical connection includes an optical interface portion having at least one optical channel and a coupling portion. The coupling portion includes a piston that is movable between a first position and a second position, a resilient member for biasing the piston to the first position and a magnet for retaining the piston at the second position. In one embodiment, the piston may be disposed in a body of the optical connection. The piston may be formed from a ferrous material and since it is not magnetic it does not attract metal trash; however, it still allows coupling (e.g., mating) of optical connections using magnetic retention. Additionally, the piston may optionally include a cover portion if desired.
