  • Patent number: 11428872
    Abstract: An optical connector includes a first attachment area for receiving and permanently attaching to an optical waveguide. A light coupling unit is disposed and configured to move translationally and not rotationally within the housing of the connector. The light coupling unit includes a second attachment area for receiving and permanently attaching to an optical waveguide received and permanently attached at the first attachment area. The light coupling unit also includes light redirecting surface. The light redirecting surface is configured such that when an optical waveguide is received and permanently attached at the first and second attachment areas, the light redirecting surface receives and redirects light from the optical waveguide. The optical waveguide limits, but does not prevent, a movement of the light coupling unit within the housing.

  • Publication number: 20210278606
    Abstract: (Problem) To provide an optical ferrule that can easily accommodate multicore optical fibers, without an accompanying increase in the number of components. (Resolution Means) The optical ferrule 1 includes a guide opening 14 formed by an upper wall 10, a bottom wall 11, and a pair of side walls 12 and 13; a guide part 15 that extends forward from the upper wall 10 and the guide opening 14; and an optical coupler 20 provided on the upper surface of the upper wall 10. The optical coupler 20 has a waveguide aligning part 21 that aligns and holds an optical waveguide 2, and a light direction converter 22 that changes the direction of light from the optical waveguide 2 and emits the light toward an opposing optical ferrule 1.
