Abstract: A fiber array unit, and a method and apparatus for fabricating the fiber array unit. The fiber array unit includes optical fibers that define a two-dimensional array of fiber end faces, and are encapsulated by a matrix that holds the optical fibers in place. The fiber array unit is fabricated by seating optical fibers in grooves of an arcuate surface, and applying an amount of uncured matrix thereto.

Overhanging portions of the bent laminate are bent into contact with sides of the mandrel by the forming assembly to form the composite structure, the composite structure having the bend in a web of the composite structure in contact with the forming surface of the mandrel and a number of flanges in contact with the sides of the mandrel.

Abstract: Matched fiber optic connectors are formed by aligning separate fiber bodies and then cutting optical fibers secured in the separate fiber bodies. The matched pair of fiber optic connectors are capable of supporting high-fiber count connectivity. The process includes placing optical fibers into a first fiber body aligned with a second fiber body with the optical fibers traversing a predetermined gap between the first end face and the second end face of the fiber bodies and securing the optical fibers to the fiber bodies using an adhesive. The optical fibers are cut at the predetermined gap between the aligned end faces of respective fiber bodies, thereby creating a first fiber optic connector having the first ends of the cut optical fibers matched and suitable for optical mating with the second ends of the cut optical fibers in a second fiber optic connector.
