  • Patent number: 9645338
    Abstract: Disclosed are optical ports and devices using the optical ports. The optical port includes a mounting body having a first pocket and at least one mounting surface for securing the optical port, one or more optical elements, and a first alignment feature disposed in the pocket, wherein the alignment feature includes a piston that is translatable during mating. The one or more optical elements may be an integral portion of the mounting body or a discrete lens. In other embodiments, the mounting body may include a plurality of pockets and one of the pockets may include a magnet for securing a plug to the optical port. The optical port may optionally have a minimalist optical port footprint so that the complimentary mating optical plug engages a portion of the frame during mating.

  • Patent number: 9645339
    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.

  • Patent number: 9568678
    Abstract: Disclosed are lens blocks and methods for making the same. In one embodiment, the lens block includes at least one optical channel having an optical interface portion on a first side, and one or more magnetic materials attached to the lens block. In one embodiment, the lens block may include one or more opening for receiving the one or more magnetic materials. The one or more openings may be located on any suitable side of the lens block as desired. The magnetic materials provide attachment with a complimentary device having an optical interface. Consequently, the lens block allows for quick and easy assembly along with a robust structure for a large number of mating/unmating cycles. In other embodiments, the lens blocks disclosed may further include one or more electrical contacts for making a hybrid connection.

  • Patent number: 9547139
    Abstract: Optical couplings for optically coupling one or more devices are disclosed. According to one embodiment, an optical coupling includes an optical coupling body, an optical interface, and a coded magnetic array located at the optical coupling body. The coded magnetic array has a plurality of magnetic regions configured for mating the optical interface.

  • Patent number: 9529159
    Abstract: Optical fiber ferrules with complementary mating geometry that are suitable for making optical connections are disclosed along with fiber optic connectors and cable assemblies using the same. In one embodiment, the fiber optic ferrule includes a body having a plurality of optical pathways and a mating geometry that includes at least one slot monolithically formed in the body of the fiber optic ferrule. The slot of the ferrule permits a relatively high number of mating/unmating cycles without generating excessive wear and debris, thereby making it suitable for consumer electronic devices or the like. The disclosure is also directed to fiber optic connectors and cable assemblies using the ferrule.

  • Patent number: 9507096
    Abstract: Embodiments disclosed herein include fiber optic connectors employing a movable optical interface connected by optical fibers to a fiber optic cable, components and methods. In one embodiment, the movable optical interface moves between an extended position for cleaning by the user of the movable optical interface and a retracted position to optically connect the fiber optic connector to an optical device in a mechanically-secure manner. Because the fiber optic cable employs the movable optical interfaces, embodiments described herein involve one or more fiber protection features to prevent optical fiber attenuation and/or damage to the end portions of the optical fibers.
