Fiber End Held In Ferrule Patents (Class 385/72)
  • Patent number: 10705297
    Abstract: A method of launching a spacecraft into low Earth orbit using a non-line-of-sight optical power transfer system. The method includes generating optical power at a base station and using an optical fiber to transmit the optical power generated to a launch vehicle via an actively cooled fiber spooler thereon. The optical power received by the launch vehicle is converted to another form of energy usable by the launch vehicle. The optical power is optically focused into a reaction chamber to impinge on a refractory target. A working fluid is regeneratively fed to a heat exchanger contained within the actively cooled fiber spooler. The working fluid is pre-heated within the heat exchanger and injected into the reaction chamber where the working fluid heats and expands. The exhaust is channeled through a rocket nozzle to produce thrust. In an alternative embodiment, the optical fiber expended during launch of a spacecraft is recovered.

  • Publication number: 20140369648
    Abstract: A fiber optic plug, suitable for multi-core fiber (MCF), is structured to hold satellite cores of the MCF in a precise angular positions so as to attain suitable alignment with satellite cores of a mating connector. The plug includes features to permit a ferrule holding the MCF to move longitudinally relative to the connector's housing, so that a spring may control a mating force to an abutting ferrule of a mating connector. The ferrule may be held by ferrule barrel having splines projecting away from an outer peripheral surface. The splines may slide longitudinally within notches of the connector housing or a strength member attached to the connector housing. The notches and splines have a tight tolerance, so that the satellite cores remain in a desired, set angular position.

    Abstract: A ferrule fixing member for fixing a ferrule to a holding member with a holding hole into which the ferrule is inserted. The ferrule fixing member includes a first plate part and a second plate part configured to face each other while sandwiching an resilient member arranged on an outer periphery of the ferrule in a radial direction thereof, a pressing part configured to press the resilient member such that the ferrule is pressed against a bottom side of the holding hole by a resilient force of the resilient member, a locked part configured to be engaged with a locking part formed in the holding member, and an extending part configured to extend from the second plate part to the locked part. The locking of the locked part and the locking part is released by moving the first plate part and the second plate part close to each other.

  • Patent number: 8858089
    Abstract: An optical fiber cable connector includes a ferrule with a guide hole that is shaped to closely receive a multicore fiber having a flat side indicative of the rotational orientation of the cores of the multicore fiber. The ferrule includes a flat surface at one side of the guide hole, corresponding in position to the flat side of the multicore fiber. Installing the multicore fiber into the guide hole with its flat side abutting the flat surface along the side of the guide hole provides alignment of the cores with respect to an optical component to which the multicore fiber endface is to be connected.

  • Patent number: 8858090
    Abstract: Ferrule holders with an integral lead-in tube employed in fiber optic connector assemblies, and related components, connectors, and methods are disclosed. By integrating the integral lead-in tube as part of the ferrule holder, the integral lead-in tube may be less expensive to manufacture and easier to install. The integral lead-in tube may also be less susceptible to inadvertent removal by friction with a bonding agent syringe or by vibration during shipment. The ferrule holder may include a ferrule holder body and integral lead-in tube. The integral lead-in tube may guide an optical fiber from a rear end of a fiber optic connector to an internal passage of the ferrule holder, where the optical fiber may be further guided to a ferrule for precise alignment. The integral lead-in tube may also protect the optical fiber during installation, shipment, and use in the fiber optic connector.
