  • Patent number: 4790622
    Abstract: An optical fiber contact for terminating an optical fiber includes a solid multi-part thermoset mixture in a cavity in a front portion of the contact, an optical fiber being terminated by heating the thermoset so as to cause it to soften and liquify and subsequently inserting an optical fiber through the contact. The thermoset when liquified chemically reacts so as to form an epoxy adhesive which secures the optical fiber within the contact and keeps the optical fiber in place even when subjected to extremely wide temperature variations.
    Type: Grant
    Filed: November 20, 1985
    Date of Patent: December 13, 1988
    Assignee: Raychem Corp.
    Inventors: Frank H. Levinson, Pravin Soni, Adam C. Tanous, Richard J. McCrae, Mark Ostasiuk
  • Patent number: 4735480
    Abstract: A connector for optically connecting first and second optical fiber contacts terminating first and second optical fibers includes a split ring comprising first and second split ring halves disposed around each of the contacts such that an enlarged internal bore of the split ring encloses a flange of the contact so as to allow limited relative longitudinal movement between the contact and the split ring. The split ring allows a nut to be disposed over an end of the contact prior to assembling the split ring about the contact which allows the construction to be reduced in size.
