  • Patent number: 10598865
    Abstract: An optical fiber connection system includes a first and a second optical fiber, each with end portions that are terminated by a first and a second fiber optic connector, respectively. A fiber optic adapter connects the first and the second fiber optic connectors. A fiber alignment apparatus includes V-blocks and gel blocks. Each of the fiber optic connectors includes a connector housing and a sheath. The end portions of the optical fibers are positioned beyond distal ends of the respective connector housings. The sheath is slidably connected to the connector housing and slides between an extended configuration and a retracted configuration. The sheath covers the end portion of the respective optical fiber when the sheath is at the extended configuration and exposes the end portion when at the retracted configuration. The end portions of the optical fibers are cleaned when slid between the V-blocks and the gel blocks.

  • Patent number: 10598864
    Abstract: Aspects of the present disclosure relate to detecting an optical signal and/or optical power in a ferrule-less optical fiber. In certain embodiments, one or more optical detectors are incorporated into an adapter that is configured to interface with a connectorized or non-connectorized ferrule-less optical fiber. The optical detector detects the presence or absence, and/or the optical power level, of the optical signal being transmitted through ferrule-less optical fiber and produces an electrical output representative of the detected optical signal.

  • Patent number: 10591678
    Abstract: An optical connector includes a first sub-assembly that is factory-installed to a first end of an optical fiber and a second sub-assembly that is field-installed to the first end of the optical fiber. The optical fiber and first sub-assembly can be routed through a structure (e.g., a building) prior to installation of the second sub-assembly. The second sub-assembly interlocks with the first sub-assembly to inhibit relative axial movement therebetween. Example first sub-assemblies include a ferrule, a hub, and a strain-relief sleeve that mount to an optical fiber. Example second sub-assemblies include a mounting block; and an outer connector housing forming a plug portion.
