    Abstract: A unitary optical ferrule is molded to include one or more elements for receiving and securing one or more optical waveguides one or more elements for affecting one or more characteristics of light from the optical waveguide while propagating the light within the ferrule. The optical ferrule also includes one or more first alignment features and one or more second alignment features that, when the ferrule is mated with a mating ferrule, each controls alignment of the ferrule with the mating ferrule along three mechanical degrees of freedom. The surface of the optical ferrule can be divided along the thickness axis into a first section and an opposing second section, wherein the first section of the surface includes the receiving and securing elements, the light affecting elements, and the first alignment features and the second section of the surface includes the second alignment features.

    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 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 ferrule (10) has a receiving area for receiving and securing an optical waveguide (20) and an optical element (13) for receiving light from an optical waveguide received and secured at the receiving area and changing at least one of a divergence and a propagation direction of the received light. A plurality of registration features (30, 31, 32, 33, 34) are configured to permit a stacking of the ferrule in a stacking direction such that the ferrules in the stack are aligned relative to each other along a length of the ferrule and along a direction perpendicular to the stacking direction.

    Abstract: An electrical contact terminal includes a base portion for positioning and retaining the electrical contact terminal within a connector housing, an insulation displacement connecting portion extending upwardly from the base portion and comprising a pair of spaced apart arms defining an opening therebetween for receiving and making electrical contact with an electrical conductor, and a contact portion extending downwardly from the base portion and configured to float when the electrical contact terminal is retained and positioned within a connector housing. The contact portion includes a first arm, a second arm, and an arcuate base portion. The first arm extends downwardly and includes a first end attached to the base portion and an opposite second end. The second arm extends downwardly and includes a free first end closer to the base portion and an opposite second end farther from the base portion. The second arm is configured to deflect when making electrical contact with a mating contact pin. The arcuate base portion connects the second ends of the first and second arms.
