    Abstract: Ferrules, alignment frames and connectors having at least one flexing element are provided. A ferrule or an alignment frame may include a body and first and second flexible arms, and a connector may include the ferrule or the alignment frame. A ferrule may have a first flexible arm that has a first fixed end attached to a first side of the body of the ferrule and an opposite first free end, and may have a second flexible arm having a second fixed end attached to a second side of the body, opposite the first side, and an opposite second free end. When the ferrule is mated with a mating ferrule, the first and second flexible arms are flexed away from the respective first and second sides of the body, and the first and second free ends contact the mating ferrule.

    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: An optical ferrule includes an optical coupling member with a light redirecting element that redirects input light from a waveguide toward an output window. The optical coupling member has a mating surface configured to slidably mate with a mating optical coupling member along a longitudinal axis of the optical ferrule. The optical ferrule also includes at least one stacking member along a longitudinal edge of the optical coupling member. The stacking member has a distal end extending beyond one of the mating surface and a top surface opposed to the mating surface. The stacking member also has a contact surface opposed to the distal end. The contact surface is configured to rotatably interface with a corresponding distal end of a of an adjacently stacked optical ferrule.

    Abstract: An opto-electronic assembly includes a substrate having a plurality of first optical waveguides, a cradle, and a first cover encapsulating at least portions of the first optical waveguides and the cradle. The cradle is bonded to the substrate and defines a pocket therein having an opening. The pocket is configured to receive an optical ferrule through the opening and align the optical ferrule to the first optical waveguides. The first cover includes an aperture exposing the opening of the pocket, such that when the optical ferrule is received in the pocket through the opening and secured therein and a plurality of second optical waveguides are attached to the optical ferrule, the opto-electronic assembly is configured to transfer light between the pluralities of first and second optical waveguides.
