    Abstract: An optical ferrule configured to move along a mating direction to mate with a mating optical ferrule. The optical ferrule includes an attachment portion for receiving and securing one or more optical waveguides. First and second engagement portions are formed integrally with the optical ferrule and spaced apart from each other along the mating direction. First and second engagement portions are formed integrally with the mating optical ferrule and spaced apart from each other along the mating direction. When the optical ferrule mates with the mating optical ferrule, the first and second engagement portions of the optical ferrule engage the respective second and first engagement portions of the mating optical ferrule. The engagement of the engagement portions of the optical ferrules prevents each of the optical ferules from moving relative to the other optical ferrule along at least mutually orthogonal first and second directions orthogonal to the mating direction.

    Abstract: A ribbon cable with a plurality of spaced apart substantially parallel insulated conductors. The parallel insulated conductors extend along a length of the cable and arranged along a width of the cable. Each insulated conductor has a central conductor surrounded by a structured insulative material formed directly onto the central conductor along substantially the entire length of the cable. The structured insulative material has a plurality of ridges extending from the central conductor along different azimuthal directions. Each pair of adjacent ridges define an angle θ there between greater than about 10 degrees.

    Abstract: An optical connector includes a housing having a resilient member and an optical ferrule. The optical ferrule includes a plurality of attachment areas for receiving and securing a plurality of optical waveguides and a light redirecting side for changing a direction of light received from an optical waveguide. The optical connector is configured such that when an optical waveguide is received and secured in any of the attachment areas and light from the optical waveguide propagates along an optical path, the resilient member is not in the optical path. When the optical ferrule mates with a mating optical ferule, the resilient member is resiliently deformed to resiliently force the optical ferrule against the mating optical ferrule.
