Abstract: An optical assembly includes an optical ferrule configured to receive light from an optical waveguide and including at least four ferrule alignment features; and a cradle securing the optical ferrule therein and configured to align the optical ferrule to an optical component, the cradle including at least four cradle alignment features configured to make contact or near contact with the at least four ferrule alignment features in a one to one correspondence in at least four corresponding contact regions, such that as a temperature of at least one of the cradle and the optical ferrule changes sufficiently, the corresponding alignment features of the optical ferrule and the cradle slide relative to each other causing the corresponding alignment features of the optical ferrule and the cradle to move to define corresponding traversed regions, such that when extended, the traversed regions of the at least four ferrule alignment features and the at least four cradle alignment features pass within 20 microns of a same first point.

Abstract: An optical cable subassembly includes one or more optical waveguides, at least light coupling unit comprising a first attachment area permanently attached to the optical waveguides, and at least one cable retainer comprising a second attachment area permanently attached to the optical waveguides and adapted to be installed in a housing. A length of the optical waveguides between the first attachment area and the second attachment area allows a bend in the optical waveguides that provides a predetermined mating spring force at a predetermined angle of the light coupling unit when installed in the housing.

Abstract: A light coupling element including a plurality of waveguide attachment features and a light redirecting member is described. Each attachment feature has an entrance end opposite a terminal end. The entrance ends are arranged at a pitch Pe. The light redirecting member is disposed closer to the terminal ends, and farther from the entrance ends, and includes an input surface, a reflecting side and an exit surface. When a waveguide is attached at each attachment feature, a central light ray emitted by each waveguide enters the light redirecting member through the input surface, is redirected by the reflecting side and exits the light redirecting member at the exit surface, the central light ray intersecting the exit surface at an exit point, each attachment feature corresponding to a different exit point at the exit surface. The exits points are arranged at a pitch Px not equal to Pe.

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: An optical ferrule includes at least one light affecting element configured to affect one or more characteristics of light from an optical waveguide as the light propagates in the optical ferrule, the light affecting element having an input surface. At least one receiving element receives and secures the optical wave guide to the ferrule so that an output surface of the waveguide is optically coupled to the input surface of the light affecting element. A waveguide stop limits movement of the wave guide toward the input surface of the light affecting element when the optical waveguide is installed in the receiving element. A space between the output surface of the optical waveguide and the input surface of the light affecting element is inaccessible to the optical waveguide when the optical waveguide is installed in the receiving element.

Abstract: A unitary optical ferrule is molded to include one or more elements for receiving and securing one or more optical waveguides one or more elements for affecting one or more characteristics of light from the optical waveguide while propagating the light within the ferrule. The optical ferrule also includes one or more first alignment features and one or more second alignment features that, when the ferrule is mated with a mating ferrule, each controls alignment of the ferrule with the mating ferrule along three mechanical degrees of freedom. The surface of the optical ferrule can be divided along the thickness axis into a first section and an opposing second section, wherein the first section of the surface includes the receiving and securing elements, the light affecting elements, and the first alignment features and the second section of the surface includes the second alignment features.

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: 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.
