  • Method and apparatus for precision injection molding of fiber optic ferrules
    Patent number: 6284160
    Abstract: An apparatus for injection molding of a fiber optic ferrule including the use of adjustable core and receiver members to precisely locate a core pin and also a projecting wire member in a mold where the core pin defines an interior passage in the molded ferrule and the projecting wire forms a small diameter longitudinal hole in the ferrule communicating with an outer end of the interior passage so that the interior passage and small diameter hole are precisely located relative to the body of the molded ferrule.
    Type: Grant

  • Method and apparatus for precision injection molding
    Patent number: 6277308
    Abstract: A method and apparatus for injection molding of a fiber optic ferrule including the use of adjustable core and receiver members adjustable from the exterior of the mold to precisely locate a projecting wire member in a mold where a score pin defines an interior passage in the molded ferrule and the projecting wire forms a small diameter longitudinal hole in the ferrule communicating with an outer end of the interior passage so that the interior passage and small diameter hole are precisely located relative to the body of the molded ferrule.

  • Snap-in coupling
    Patent number: 6173099
    Abstract: A coupling is provided having a one-piece body, with a first segment having a first chamber for receiving an optical connector and ferrule, a second segment having a second chamber for receiving an alignment sleeve that retains and interconnects the ferrules, a third segment substantially similar to the first segment and having a third chamber for receiving a second optical connector and ferrule, wherein said first, second and third chambers are aligned longitudinally across the one-piece body, and a resilient arm extends from the one-piece body to allow the coupling of the invention to be received by a coupling aperture.

  • Fiber optic connector with sliding key
    Patent number: 5335301
    Abstract: A duplex optical fiber connector terminates two single or multi-mode optical fibers of a cable and is adapted to be joined to a receptacle being polarized correspondingly to a keying element of the connector. The keying element is slidable into multiple positions so that a recess in the keying element mates with a correspondingly positioned rib of a receptacle. The recess of the keying element is positioned within a channel axially extending on the connector exterior body.
