  • Patent number: 8768125
    Abstract: A guide pin for mating multi-fiber optical ferrules includes a first end, a second end and a flexile feature adjacent to the second end. The first end has a first end width and the second end has a first engagement width and may change to a second engagement width while engaging a guide pin bore in a ferrule. The change in width permits the guide pin to engage and axially align with guide pin bores of varying diameters to achieve reliable optical mating of optical wave guides.

  • Publication number: 20140169745
    Abstract: Disclosed are optical ports and devices having a minimalist footprint. Specifically, the optical ports and devices have a footprint where the optical elements are exposed at a frame of the device. Additionally, a frame of the device provides a portion of the mating surface for engaging a complimentary optical plug during mating with the optical port on the device. This minimalist footprint advantageously allows for a smaller portion of the optical port to be exposed to the environment and subject to damage and/or wear. Further, the optical port provides a clean and sleek optical port on the device with a relatively small surface that may be cleaned or wiped by the user as necessary.

  • Publication number: 20140112623
    Abstract: Disclosed are optical connections having a coupling portion that includes a piston and a magnet along with complimentary optical connections. In one embodiment, the optical connection includes an optical interface portion having at least one optical channel and a coupling portion. The coupling portion includes a piston that is movable between a first position and a second position, a resilient member for biasing the piston to the first position and a magnet for retaining the piston at the second position. In one embodiment, the piston may be disposed in a body of the optical connection.
