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 plug connector for connecting optical fibers to an electrical receptacle connector includes a housing defining a cavity therein. At least one printed circuit board (PCB) is disposed in the housing cavity. The PCB includes one or more optoelectronic components disposed on its top surface and electrical contacts disposed proximate a mating edge of the PCB for mating with the receptacle connector. The electrical contacts are electrically connected to the one or more optoelectronic components. One or more optical fibers enter the housing cavity through a housing opening and are optically coupled to the optoelectronic components. A structure comprising a top surface is disposed within the housing cavity between the housing opening and the PCB. The plurality of the optical fibers extends over the top surface of the structure and over at least a portion of the top surface of the PCB. The plurality of the optical fibers is separated from the top surface of the PCB by a first minimum distance and from the top surface of the platform by a second minimum distance less than the first minimum distance.

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: 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 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: A light coupling element including a groove and a light redirecting member is described. The groove is for receiving and aligning an optical waveguide and incudes an open front end and a back end. The light redirecting member includes an input side for receiving light from an optical waveguide received and supported in the groove and a light redirecting side for changing a direction of light received from the input side. The groove may include a bottom surface extending between the front and back ends of the groove and including a raised bottom surface portion raised upwardly relative to an unraised bottom surface portion. The unraised bottom surface portion of the bottom surface may be disposed between the raised bottom surface portion of the bottom surface and the input side of the light redirecting member. Optical coupling assemblies including the light coupling element and an optical waveguide are described.
