Abstract: Optical connectors are provided for connecting sets of optical waveguides (110), such as optical fiber ribbons to each other, to printed circuit boards, or to backplanes. The provided connectors include a waveguide alignment member (105) for receiving and aligning a plurality of optical waveguides (110) such that central light rays of light exiting the plurality of optical waveguides propagate along a same incident direction (115) in a same incident plane XY. The optical connectors also include a light redirecting side that comprises a plurality of segments (130) forming a row of segments (130a, 130b, . . . ), each segment corresponding to a different optical waveguide. A first segment (130a) redirects light along a first redirected direction (140a) and a second segment (130b) redirects light along a second redirected direction (140b) different from the first redirected direction. Other segments redirect light to either a first redirected direction or a second redirected direction. The light is redirected to two or more rows of optical lenses (150). Also provided is a cable assembly that includes a provided connector and a plurality of optical waveguides permanently attached to the connector.

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.

Abstract: A fiber optic ribbon is disclosed and includes a plurality of optical fibers extending along a first axis and arranged along an orthogonal second axis at a pitch P. Each optical fiber includes a core surrounded by a cladding surrounded by a buffer, the buffer has a nominal diameter D0 substantially equal to P. The buffer is stripped between a buffer-end location on the fiber and a free end of the fiber to form a stripped section. The buffer is distorted at the buffer-end location, such that at the buffer-end location, a width W of the buffer in the second axis is less than D0.

Abstract: A covering latch configured to secure an optical ferrule received in an optical cradle including a cover portion configured to extend across and cover at least a portion of the optical ferrule, a pair of rear arms and an opposing elastic front arm extending downwardly from proximate respective rear and front ends of the cover portion for engaging respective rear and front sides of the optical cradle. The pair of rear arms define an opening therebetween for receiving an optical waveguide attached to the optical ferrule, such that pulling the cover portion rearwardly, causes the elastic front arm to flex, and the rear arms to disengage from the rear side of the optical cradle.

Abstract: An optical cradle is configured to mate with an optical ferrule and permanently bond to a substrate so that light from an optical waveguide coupled to the optical ferrule exits the optical ferrule and couples to an optical component on the substrate after entering the optical cradle at a first location of the optical cradle. The optical cradle includes at least one fulcrum extending from a bottom surface of the optical cradle and configured to make contact with the substrate and allow a rotation of the optical cradle about the contact to angularly align the optical cradle to the optical component without substantially changing a distance, d, between the first location and the optical component.

Abstract: An optical connector comprises one or more optical cables disposed within a housing. Each optical cable includes an array of at least one optical waveguide and at least one optical ferrule attached to the array of optical waveguides. The housing includes a first housing portion and a second housing portion engaged with the first housing portion. The second housing portion comprises at least one carrier and one frame. The carrier and frame of the second housing portion are configured to support the one or more optical cables. The first housing portion and the second housing portion are configured such that mechanical engagement of the first housing portion with the second housing portion moves the carrier relative to the frame. Movement of the carrier relative to the frame causes a bend in each optical waveguide and rotation of each ferrule. The bend provides a predetermined spring force of the optical waveguides at a predetermined angle of the ferrule.

Abstract: An optical ferrule assembly includes a hybrid optical ferrule having a glass portion assembled to a polymeric portion. The polymeric portion includes a groove for receiving and supporting an optical fiber having opposing open front and back ends. A light redirecting member includes an input surface for receiving light from the optical fiber and a light redirecting side. The open back end of the groove and the input surface define a recessed region therebetween. The glass portion includes an optically transparent glass insert disposed in the recessed region conforming in shape to an internal shape of the recessed region. An optical fiber is received and supported in the groove. The optical fiber includes a fiber end laser welded to the glass insert so that a central light ray from the optical fiber propagates through the glass insert before being received and redirected by the light redirecting side.
