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: An optical communication subassembly includes one or more optoelectronic devices, one or more optical elements, and a transceiver light coupling unit. Each optical element is configured to change a divergence of the outgoing light relative to a divergence of the incoming light and is spaced apart from and optically aligned with a corresponding optoelectronic device. The transceiver light coupling unit has a mating surface configured for mating with a connector light coupling unit attached to an optical waveguide. A mating direction of the optical light coupling unit forms an angle with the mating surface of the transceiver light coupling unit such that when the connector light coupling unit mates with the transceiver light coupling unit, the angle between the mating direction of the connector light coupling unit and the mating surface of the transceiver light coupling unit causes the optical waveguide to bend.

Abstract: Optical connectors are provided for connecting sets of optical waveguides, such as optical fiber ribbons to each other, to printed circuit boards, or to backplanes. 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: An optical ferrule has a different thermal expansion coefficient than a substrate to which a optical device is mounted, the ferrule optically coupling the device to one or more optical fibers. The optical ferrule includes and/or a cradle in which the ferrule is mounted include lateral and longitudinal engagement feature that ensure alignment with the optical device at an operating temperature, the ferrule expanding relative to the substrate when transitioning to the operating temperature.

Abstract: An optical ferrule comprises first and second compound stop features respectively disposed at opposing sides of the optical ferrule. Each compound stop feature has upper and lower contact surfaces. The lower contact surface is offset below the mating surface of the optical ferrule along a thickness axis perpendicular to the mating surface. The upper contact surface is offset above the mating surface along the thickness axis. The lower contact surface is offset forward from the upper stop surface along a mating direction of the optical ferrule. A connecting surface connects the upper contact surface and the lower contact surface.

Abstract: A molded optical ferrule configured to mate with a mating component includes a top surface, a bottom surface opposite the top surface, and a plurality of side surfaces joining the top and bottom surfaces. The plurality of side surfaces includes a plurality of first side surface portions and a plurality of second side surface portions. The first side surface portions make a first angle greater than zero degrees with a thickness direction of the optical ferrule, the first angle assisting in the removal of the optical ferrule from a mold. The plurality of second side surface portions extends outwardly from the first side surface portions and makes a second angle less than the first angle with the thickness direction. When the optical ferrule mates with the mating component, at least some of the second, but not the first, side surface portions contact corresponding side surface portions of the mating component.

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 waveguide 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 waveguide 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: An optical assembly includes a substrate with a plurality of optical waveguides, and a unitary optics array assembled to the substrate. The unitary optics array includes a support portion attached to the substrate, an input surface facing a first waveguide end of each optical waveguide, a redirecting surface, and an output surface. For each optical waveguide, the input surface is configured to receive and transmit a central light ray propagating through and emitted from the first waveguide end of the optical waveguide, and the redirecting surface is configured to receive the central light ray transmitted by the input surface along a first direction and redirect the received central light ray along a second direction different from the first direction, the redirected central light ray exiting the optics array as an output central light ray through the output surface.
