Abstract: A connector is disclosed that includes a housing and first and second attachment areas located in the housing and spaced apart from each other along the mating direction of the connector. The second, but not the first, attachment area is designed to move relative to the housing. The connector further includes an optical waveguide that is permanently attached to, and under a first bending force between, the first and second attachment areas. The connector also includes a light coupling unit located in the housing for receiving light from the optical waveguide and transmitting the received light to a mating connector along a direction different than the mating direction of the connector. The mating of the connector to the mating connector causes the optical waveguide to be under a greater second bending force between the first and second attachment areas.

Abstract: An optical ferrule (200) has opposing major top (10) and bottom (20) surfaces where the bottom surface includes discrete spaced apart first (90) and second (100) platforms arranged along a mating direction of the optical ferrule (200). During a mating of the ferrule (200) with a mating optical ferrule (200′), the first (90) and second (100) platforms of the ferrule (200) slide against corresponding respective first (90′) and second (100′) platforms of the mating ferrule (200′). Upon full mating of the ferrule (200) with the mating ferrule (200′), the second platforms (100, 100′) of the ferrule and the mating ferrule remain in contact with and rest on each other, and the first platform (90, 90′) of neither ferrule makes contact with the other ferrule.

Abstract: An optical communication subassembly includes one or more optoelectronic devices, one or more optical elements, and a transceiver light coupling unit. Each optical element is configured to change a divergence of the outgoing light relative to a divergence of the incoming light and is spaced apart from and optically aligned with a corresponding optoelectronic device. The transceiver light coupling unit has a mating surface configured for mating with a connector light coupling unit attached to an optical waveguide. A mating direction of the optical light coupling unit forms an angle with the mating surface of the transceiver light coupling unit such that when the connector light coupling unit mates with the transceiver light coupling unit, the angle between the mating direction of the connector light coupling unit and the mating surface of the transceiver light coupling unit causes the optical waveguide to bend.

Abstract: A hybrid connector includes a connector housing, one or more first connection elements configured to transfer a first type of energy or a fluid, and one or more second connection elements configured to transfer a second type of energy, different from the first type of energy, or the fluid. The first connection elements are rotationally fixed and the second connection elements are configured to rotate around an axis that is substantially perpendicular to a mating axis of the housing.

Abstract: The disclosure generally relates to individual optical waveguides, sets of optical waveguides such as optical fiber ribbons, and fiber optic connectors useful for connecting individual optical waveguides or multiple optical fibers such as in optical fiber ribbon cables. In particular, the disclosure provides an efficient, compact, and reliable optical fiber connector that exhibits a low insertion loss for use with multimode optical waveguides. The optical connectors incorporate a unitary light coupling unit combining the features of optical fiber alignment, along with redirecting and shaping of the optical beam.

Abstract: A connector is disclosed that includes a light coupling unit designed to receive light from an input side of the light coupling unit and transmit the received light to a mating connector from an output side of the light coupling unit along a direction different than the mating direction of the connector. The light coupling unit rotates when the connector mates with the mating connector.

Abstract: An optical cable subassembly includes one or more optical waveguides, at least light coupling unit comprising a first attachment area permanently attached to the optical waveguides, and at least one cable retainer comprising a second attachment area permanently attached to the optical waveguides and adapted to be installed in a housing. A length of the optical waveguides between the first attachment area and the second attachment area allows a bend in the optical waveguides that provides a predetermined mating spring force at a predetermined angle of the light coupling unit when installed in the housing.
