44982607, Feb 12, 1985

Filed:

May 10, 1982

Appl. No.:

6/376866

Inventors:

John S Doty - Yucaipa CA

Assignee:

Hughes Aircraft Company - El Segundo CA

International Classification:

B24B 4106

US Classification:

51217R

Abstract:

The axial positions of two or more fibers are simultaneously controlled in three grinding or polishing stages. The fibers (72) are first ground flush with the guide (120) in which they are housed. The fiber ends and faces of the guides are then ground flat and square. The fibers are thereafter polished to their optical quality and required length. The tool for accomplishing these steps includes a retainer (74) which holds the assembly (73) of fiber optic ferrules (70) and their optical fibers (72) therein at a tool surface (16). This tool surface is protected by a guard (18) from being too rapidly ground away while the fibers and fiber/guide combinations are ground flush with the surface. The surface and its retained guides and fibers are then axially moved to an unprotected position (FIG. 3) so that the surfaces and the fibers within their ferrules may be polished on a suitable polishing wheel or similar device.

International Classification:

G02B 514

US Classification:

350 9620

Abstract:

An interchangeable multi-channel hermaphroditic fiber optic connector (10) for cables (12), having different numbers of optical fibers (18) and contacts (22) therefor, comprises a connector shell (34) having a specifically configured interior surface (38) and a plurality of inserts (26) each having an exterior surface (36) which is configured substantially as the connector shell's interior surface. This substantially similar configuration permits interchangeable insertion of any of the inserts within the connector shell. The inserts have different numbers of cavities (28) in order to accommodate any number of optical fibers and their contacts, without needing to change the entire connector structure. A strain relief (62, 64, 66, 100) is coupled to the inserts, and an uncoupling prevention mechanism (104, 108) is housed about the strain relief and the insert to isolate turning moments exerted by a nut (124) on the exterior of the connector from being exerted on, and from uncoupling the internally secured members (26, 62, 64, 66).

International Classification:

B26F 300

US Classification:

29469

Abstract:

The present apparatus and method make it extremely easy for a worker, even when located in a manhole or on a telephone pole, to rapidly achieve a perfect break in an optical fiber and at a precisely predetermined position relative to a connector means. The breaking is the same, regardless of the upright, inverted or inclined position of the tool. Only a single motion of the blade is required at any desired speed, and there is no necessity for the blade to contact the fiber at a pressure within certain limits. These and other major results are obtained by clamping an optical connector element to the optical fiber before breaking is effected, and then removably securing the connector element to the breaker at a precisely known position which is correlated to the location of the scoring blade and to the characteristics of the connector. The fiber is then clamped, bent, tensioned and scored in response to a single squeezing and releasing motion by one hand of the operator--these actions being substantially entirely unaffected by excessively hard squeezing forces. The scoring is effected by a hard-mounted tungsten carbide blade which moves, in an arcuate path, toward and across the tensioned fiber.
