Publication number: 20190094471Abstract: 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.Type: ApplicationFiled: November 28, 2018Publication date: March 28, 2019Inventors: Michael A.

Publication number: 20190079254Abstract: 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.Type: ApplicationFiled: November 12, 2018Publication date: March 14, 2019Inventors: Terry L.
