Abstract: A method of forming a molded, field-installable optical connector. The method uses a support assembly which includes a wire mandrel (10), a mandrel holder (11), surrounding a portion of the wire, and a mandrel sleeve (12), surrounding a portion of the mandrel holder and including an end surface (15). Positioned at the end surface is a watch bearing jewel (16), with an aperture (17), through which the wire is inserted. A backbone insert (19) is also located around a portion of the mandrel sleeve. The assembly is positioned within a molding apparatus including a precision frusto-conical die (25), by inserting the wire through a second jewel (26), mounted in the die. After molding, the connector, which includes the first jewel embedded at one end of the molded part and the backbone insert as a strength member, is removed from the support assembly.

Abstract: Photo-optical keyboard matrix (10) including a plurality of light transmitting optical fibers (12). The fibers are arranged in rows and columns with light generating means (14) disposed at the row terminations of the fibers and light receptors (16) are disposed at the column terminations of the fibers. The fibers are angularly cut at the matrix intersections of rows and columns to form an air prism. Individual key members, each provided with light blocking and unblocking means are movable into and out of the air prism area effectively blocking and unblocking light from generator to receptor thus providing optical keyboard switching apparatus.

Abstract: An individually armoured fiber optic core assembly (10) having a diameter not greater than 0.050" (1.72 mm) is provided as well as a process for making same. A fiber optic core (11) comprising a fiber optic element (12) and a surrounding protective layer (13) is encased within a drawn metal sheath (14) having a generally longitudinally extending seam (15). The ratio of the outside diameter of the fiber optic core (11) to the inside diameter of the metal sheath (14) is at least about 0.6:1. The fiber is formed by drawing metal strip (32') through a die (36) and simultaneously laying the core into the sheath as it is formed by the die. Optionally the sheath can be sealed by a line of solder applied along the length of the seam. Fiber optic cables comprising a plurality of individual fibers according to the invention are also described.

Abstract: In the manufacture of an optical cable element for use in an optical cable, a water-impermeable medium (5) in a liquid or semi-liquid state is applied to an advancing optical fibre (F) immediately upstream of an extruder (1) in such a way and under such a pressure that the advancing optical fibre with waterimpermeable medium therearound passes into the extruder. After a tube of polymeric material has been extruded around the advancing optical fibre (F) and the surrounding water-impermeable medium in such a way that the internal diameter of the tube is greater than the overall diameter of the optical fibre and the extruded tube has been drawn down and so treated that molecules are longitudinally oriented, the space in the tube not occupied by the optical fibre is filled with water-impermeable medium of a jellylike nature.
