Abstract
Connectors for optical cables in ribbon form and a process for making such connectors in which metal plates for the enclosing the cable ends are made by cold, plastic flow forming of grooves in the plates with a punch having ridges produced by a process which produces grooves which hold the positions of the optical fibers between the plates within narrow tolerances. In the process, a punch body with partially formed ridges is mounted on a head rotatable about the axis of the body and movable toward a grinding wheel which is movable in a path perpendicular to the direction of movement of the head toward the grinding wheel. After two opposite passes of the grinding wheel along the side of a ridge, the punch body is rotated 180 degrees, and the side of a corresponding ridge on the opposite side of the punch body axis is ground. The process is repeated with movement of the head toward the grinding wheel, which is measured, until the sides of all ridges are ground. One of the grooves receives an alignment pin, and after the fibers are assembled with the plates, the end faces of the fibers are ground.
