Patent number: 10698167Abstract: A connector device for connecting optical fiber endpieces comprising an optoelectronic chip, a fiber end piece holder and a reflection surface. The chip is oriented for emitting and/or detecting optical signals along a first propagation direction normal to a circuit board. The reflection surface changes a propagation direction of optical signals from the first propagation direction to a different, second propagation direction and/or vice versa. The connector device comprises a layered optical stack mounted to the circuit board and designed for propagation of optical signals along the first propagation direction. The connector device further comprises a coupling adapter piece mounted to the layered optical stack that holds and/or secures the fiber end piece holder in an orientation enabling propagation of signals radiation along the second propagation direction. The reflection surface for changing between both propagation directions is comprised in the coupling adapter piece.Type: GrantFiled: September 15, 2017Date of Patent: June 30, 2020Assignee: Corning Optical Communcations LLCInventors: Jeffery Alan DeMeritt, Wojciech Piotr Giziewicz, Christopher Paul Lewallen, James Phillip Luther, Jerald Lee Overcash, Rebecca Kayla Schaevitz
