Filed:

Jul 28, 1997

Appl. No.:

8/909442

Molex Incorporated - Lisle IL

International Classification:

G02B 636

US Classification:

385 78

Abstract:

An alignment system is disclosed in a connector ferrule for a fiber optic cable which includes at least one optical fiber. A ferrule body receives the cable and includes a fiber passage for receiving the optical fiber. A pin passage in the ferrule body is spaced from the fiber passage for receiving an alignment pin projecting from the ferrule body to align the body with an appropriate complementary connecting device. An alignment bushing is disposed in the pin passage for directly receiving the alignment pin. The outside dimensions of the bushing are smaller than the inside dimensions of the pin passage to define a space therebetween. A filler adhesive is applied in the space between the outside of the alignment bushing and the inside of the pin passage. Therefore, the bushing can be precisely aligned in the pin passage from exteriorly of the passage, and the filler adhesive can fix the bushing in that precise alignment interiorly of the passage.

US Classification:

385 80

Abstract:

A method is disclosed for fabricating a connector ferrule for a fiber optic ribbon cable which includes a plurality of generally parallel optical fibers in a line. A ferrule body is provided with a fiber passage which is elongated in cross-section to receive the line of optical fibers. A jacket is removed from an end portion of the fiber optic ribbon cable to expose the line of optical fibers. The ferrule body is placed in a fixture. The cable is placed in the ferrule body with the exposed line of optical fibers located in the fiber passage, and with distal ends of the exposed fibers projecting outwardly of the ferrule body. The exposed distal ends of the fibers are located on the fixture to precisely align the fibers relative to each other in the fiber passage. A filler adhesive is applied in the fiber passage about the exposed fibers to fix the fibers in the fiber passage while the fibers are held by the fixture in their precise alignment.

US Classification:

285 53

Abstract:

A fixture is disclosed for use in fabricating a connector ferrule for a fiber optic cable which includes a plurality of generally parallel optical fibers. The fixture includes a base, with a receptacle on the base for receiving and properly positioning a ferrule body. A cable locator is provided on the base at one side of the receptacle for positioning the cable inserted in the ferrule body, with exposed end portions of the optical fibers projecting from the ferrule body at an opposite side of the receptacle. A fiber aligner is provided on the base at the opposite side of the receptacle for aligning the exposed end portions of the optical fibers relative to each other and relative to the properly positioned ferrule body.

Abstract:

A connector ferrule is disclosed for a fiber optic ribbon cable which includes a plurality of generally parallel optical fibers in a line. A ferrule body receives the cable and includes a fiber passage which is elongated in cross-section to receive the line of optical fibers that are exposed by removing the jacket at an end portion of the fiber optic ribbon cable. A filler adhesive is disposed in the elongated fiber passage for fixing the fibers in the fiber passage in proper spaced relationship. Therefore, the line of fibers can be precisely aligned and relatively spaced from exteriorly of the fiber passage, and the filler adhesive can fix the fibers in that precise alignment and relative spacing interiorly of the fiber passage.

US Classification:

15 971

Abstract:

A system is provided for cleaning the end of a ferrule of a fiber optic connector mounted on a backplane of a chassis adapted for receiving a printed circuit board having a mating connector mateable with the fiber optic connector. A dummy circuit board is receivable by the chassis to replace the actual printed circuit board. A cleaner is mounted on the dummy circuit board for cleaning the end of the ferrule of the fiber optic connector when the dummy circuit board is received by the chassis.

Abstract:

A cleaner is disclosed for cleaning the end of a ferrule of a fiber optic connector. The cleaner includes a housing having a mating portion for mating the cleaner with the fiber optic connector. A supply of a cleaning medium is mounted in the housing. An advancing mechanism is mounted on the housing for advancing the cleaning medium past the ferrule end of the fiber optic connector when the cleaner is mated with the connector.
