ABSTRACT:
A fiber optic light transfer device (11) has a plurality of optical fibers (12) with end surfaces (13 and 14). A locator body (21) for the fibers has a multiplicity of parallel slots (22) through which the fibers extend and by which the fibers are located and mechanically held. Each slot has first and second supporting surfaces (24 and 25) at right angles to one another in mutually perpendicular planes. First and second reference supporting surfaces (24R and 25R) locate a reference end fiber (12R) perpendicular to a third plane that is mutually perpendicular to the other two planes and a reference ribbon in the second plane. The further end fibers are located in the first plane and at equally spaced intervals in planes parallel to the second reference plane and, when adhered to the supporting surfaces, precisely locate and mechanically hold the fibers against movement relative to one another in three mutually perpendicular planes. In one method a plurality of channel-shaped members, each containing one ribbon, are stacked one on another and cut on a diagonal to form two identical devices.
