Abstract: The present invention relates to a hybrid connector. The connector comprises an insulating housing having parallel rows of first and second terminals disposed in the housing. Each first and second terminal includes a terminal portion configured to make contact with an electrically conductive trace of a circuit board; and a mating portion configured to contact a terminal of a mating connector, the mating portions of the first terminals parallel to and facing the mating portions of the second terminals. The housing defines a cavity formed therein between the mating portions of the first and second terminals, wherein the cavity defining a cavity opening at an external surface of the housing for receiving light therefrom. An optical relay portion is disposed in the cavity, wherein the optical relay portion comprises at least one of an optical transceiver, an optical lens and an optical waveguide.

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 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 assembly includes first (102) and second (103) housings configured to move relative to each other. The first housing includes an attachment area (124) configured to permanently attach an optical waveguide (122) and having a facet (634) that optically couples the optical waveguide to the first housing. The first housing further includes an first input/output surface (112) at a non-zero angle to the facet and a light redirecting member (638) optically coupled to change a direction and divergence of light between the facet and the first input/output surface. The second housing includes a second input/output surface (113) facing and optically coupled to the first input/output surface. The first and second input/output surfaces maintain an alignment along a light propagation direction therebetween through a range of motion between the first and second housings. The second housing includes a transmission path configured to convey signals optically received or transmitted via the second input/output surface.

Abstract: Optical connectors are provided for connecting sets of optical waveguides (104), such as optical fiber ribbons to each other, to printed circuit boards, or to backplanes. The provided connectors (100) include a housing (110) that has an attachment area (102) for receiving and permanently attaching a plurality of optical waveguides. Additionally, the provided connectors include a light coupling unit (120) disposed in and configured to move with the housing. The provided connectors also include a second attachment area (108) for receiving and permanently attaching to the plurality of optical waveguides that causes each optical waveguide to be bent between the two attachment areas. The provided connectors utilize expanded beam optics with non-contact optical mating resulting in relaxed mechanical precision requirements. The provided connectors can have low optical loss, are easily scalable to high channel count (optical fibers per connector) and can be compatible with low insertion force blind mating.
