US Patent:

6758601, Jul 6, 2004

Filed:

Sep 28, 2001

Appl. No.:

09/967491

Inventors:

Marlon E. Holmquist - Gibbon MN

Assignee:

ADC Telecommunications, In. - Eden Prairie MN

International Classification:

G02B 638

US Classification:

385 75, 385 55, 385 53

Abstract:

A fiberoptic connector is constructed entirely of metal and includes structure to radiate heat. Preferably, the fiberoptic connector also includes an arrangement to indicate whether the fiberoptic connector is holding an energized optical fiber. Preferably, the heat radiating structure includes fin structure and a metal stamping projecting from the connector housing. The indicating arrangement preferably is a temperature sensitive strip secured to the housing, which changes color based upon the heat radiated by the optical fiber carried within. Methods of indicating an energized fiberoptic connector and of dissipating heat from a fiberoptic connector are provided.

Assignee:

ADC Telecommunications, Inc. - Eden Prairie MN

International Classification:

G01N 2101

US Classification:

356244, 356 731, 385147

Abstract:

Methods and apparatus fix relative rotation between an optical connector about an axis that runs longitudinally through the optical connector and an inspection machine. In one method, an optical connector is releasably secured to a cage member having an extending flange. The optical connector is mounted into an inspection machine by inserting the end surface of the connector into a connector receipt aperture of the machine, and orienting the optical connector with the cage member to position the extending flange within a void of a fixture on the machine. A kit including a cage member and a mounting plate are provided.

G02B 6/00

US Classification:

385 94, 385 78, 385139

Abstract:

A fiber optic connector assembly with a fiber optic connector mounted to a fiber optic cable and including a ferrule with an end face terminating the fiber. A plug is configured to fit about and engage the ferrule of the fiber optic connector to seal the end face from contaminants. An adhesive tape is releasably attached to the connector about the plug, holding the plug to the connector. Further, a cover assembly for a fiber optic connector mounted to an end of and terminating a fiber optic cable. The cover includes an open sided box and a lid sized to engage the open side. The box and the lid define a cavity sized to fit about and receive a fiber optic connector. The cavity has an open end adapted to receive the optical fiber cable. The fiber optic connector is held within the cavity and the cable extends through the open end, with the lid engaging the open side and sealing the cavity from contaminants outside the cavity.

International Classification:

G02B 6/36

US Classification:

385 53

Abstract:

The present invention relates to a fiber optic connector holder sized to fit within an opening for mounting a fiber optic adapter. The fiber optic connector holder is configured to permit a fiber optic connector with a dust cap positioned about a ferrule and a polished end face of an optical fiber held by the ferrule to be inserted within and releasably held by the connector holder. The present invention further relates to a system for holding fiber optic connectors including a fiber optic connector holder mounted within an opening in a bulkhead for mounting a fiber optic adapter. The fiber optic connector holder is configured to receive a fiber optic connector with a dust cap mounted about a ferrule and polished end face of an optical fiber held by the ferrule. The present invention also relates to a method of holding an optical fiber connector to a bulkhead, when the fiber optic connector includes a dust cap mounted about a ferrule and a polished end face of an optical fiber held by the ferrule.

Marlon E. Holmquist - Gibbon MN, US

Assignee:

ADC Telecommunications, Inc. - Eden Prairie MN

International Classification:

G02B 6/36

US Classification:

385 60, 385 53

Abstract:

A fiber optic connector including a ferrule surrounding an optical fiber and a hub engaging the ferrule. The hub includes a front portion having first and second surfaces and first and second tapered contact regions extending from the first and second surfaces to a front face. A housing includes an anti-rotation seat including first and second angled contact surfaces positioned at a front of the anti-rotation seat. A spring within a chamber of the housing biases the ferrule through a bore in the front of the housing. The first tapered contact region of the hub engages the first contact surface, and the second tapered contact region engages the second contact surface when the hub and ferrule are in a first rotational position so that the optical fiber is maintained at a known orientation. The tapered contact regions are planar surfaces sized smaller than the angled contact surfaces.

Abstract:

A telecommunications cabinet comprising a top, a floor, a pair of opposing sides, a front wall and a rear wall defining an interior, the front including an access door for accessing the interior. Within the interior are mounted a cable management structure, an adapter panel with an adapter configured to optical connector two optical fiber cables terminated with fiber optic connectors, and a fiber optic connector holder mounted in openings of the adapter panel. The connector holder has an opening configured to receive a fiber optic connector with a dust cap, the opening accessible from a front side of the adapter panel. A fiber optic connector including a ferrule with a polished end face holding an end of an optical fiber with a dust cap placed about the ferrule and polished end face is inserted within the opening of a fiber optic connector holder. And a fiber optic connector is inserted within the rear side of one of the adapters.
