  • Patent number: 8391708
    Abstract: Provided herein is a novel approach to simultaneous fiber presence detection and improved laser eye safety of an optical transceiver. The subject optical transceiver is fitted with at least one switch in its receptacle that controls the laser diode and indicates the presence of a fiber (or fibers) within such a receptacle. If a fiber is present within the subject module receptacle, the laser switch is permitted to be “on”, whereas the absence of a fiber will prevent the laser switch from turning on, thereby permitting effective control of the laser at a single point of failure within the entire optical transceiver system. The typical optical transceivers of today exhibit limited optical power output due to eye safety limit criteria.

  • Patent number: 8376629
    Abstract: A fiber optic connector assembly and method employing one or more fiber movement supports. The one or more fiber movement supports are each disposed around one or more optical fibers and are configured to inhibit kinks or sharp bends from occurring in the one or more optical fibers. The fiber movement support is more rigid than an optical fiber. Thus, when a force is exerted on an optical fiber in a direction angled to the axis of the optical fiber, the force is directed to the fiber movement support. The fiber movement support translates the non-axial force in a direction toward the axis of the optical fiber. This causes the optical fiber to be pushed back towards the fiber optic cable instead of the kinking or bending the optical fiber, thus avoiding or reducing high insertion losses resulting from bending of the optical fiber.

  • Patent number: 8317410
    Abstract: This disclosure describes techniques for attaching a connector to a fiber optic cable. As described herein, lengthwise slits are made into the jacket and the buffer tube of a fiber optic cable, thereby exposing interior segments of the optical fibers of the fiber optic cable. A loop is then made in the fiber optic cable at the slits. The ends of the optical fibers can then telescopically slide out the end of the fiber optic cable. When this happens, the exposed interior segments of the optical fibers slide out of the buffer tube and the jacket through the slits, forming a smaller loop within the loop. A connector may then be attached to the exposed ends of the optical fibers. When the fiber optic cable is unlooped, the exposed interior segments of the optical fibers slide back into the buffer tube and jacket. The jacket may then be resealed.
