Multifiber Ferrule Defining Alignment Holes Having A Tapered Lead-In Portion

View page
US Patent:
6350062, Feb 26, 2002
Filed:
May 7, 1999
Appl. No.:
09/307530
Inventors:
Dennis M. Knecht - Hickory NC
Joel C. Rosson - Hickory NC
Markus A. Giebel - Hickory NC
James P. Luther - Hickory NC
Karl M. Wagner - Hickory NC
Assignee:
Corning Cable Systems LLC - Hickory NC
International Classification:
G02B 636
US Classification:
385 84, 385 59, 385 60, 385 65
Abstract:
A multifiber ferrule is provided that includes a ferrule body that defines at least one elongate hole opening through the front face of the ferrule body that, in turn, includes a lead-in portion proximate the front face for guiding the respective alignment member into the elongate hole. The ferrule body at least partially defines one or more elongate holes, such as a guide pin hole or an alignment groove, each having a longitudinal axis extending therethrough. Each elongate hole includes the lead-in portion proximate the front face and an adjacent alignment portion. The lead-in portion expands radially outward from the longitudinal axis in a direction extending from the adjacent alignment portion to the front face of the ferrule body. As such, the opening of the lead-in portion through the front face of the ferrule body is larger in lateral cross-section than the opening of the lead-in portion into the adjacent alignment portion. The lead-in portion is therefore capable of guiding the respective alignment member into the adjacent alignment portion that, in turn, is sized to snugly receive the alignment member, thereby serving to properly align the ferrule with the alignment members.

US Patent:
6396993, May 28, 2002
Filed:
Dec 30, 1999
Appl. No.:
09/475915
Inventors:
Markus A. Giebel - Hickory NC
James P. Luther - Hickory NC
Brian J. Gimbel - Hickory NC
Otto I. Szentesi - Hickory NC
Assignee:
Corning Cable Systems LLC - Hickory NC
International Classification:
G02B 600
US Classification:
385136, 385139
Abstract:
The challenge of pulling an optical fiber having a connector at its terminal end without incurring damage to the fiber or connector due to excessive pulling or bending is met by introducing a breakaway feature that disconnects the connectorized fiber from the pulling mechanism upon detecting excessive force. The breakaway feature may be positioned at several locations along the pathway connecting the optical fiber and the pulling force. In one embodiment the breakaway feature is disposed on a cover over the connectorized front end of the optical fiber. In other embodiments the breakaway element is inserted along the cord connecting the connectorized optical fiber to the pulling force.

Field-Installable Fiber Optic Ribbon Connector And Installation Tool

View page
US Patent:
6439780, Aug 27, 2002
Filed:
Aug 31, 2000
Appl. No.:
09/652447
Inventors:
Ronald L. Mudd - Euless TX
Markus A. Giebel - Hickory NC
Michael de Jong - Ft. Worth TX
Assignee:
Corning Cable Systems LLC - Hickory NC
International Classification:
G02B 636
US Classification:
385 83
Abstract:
A fiber optic cable connector for an optical ribbon comprises a multi-fiber ferrule having a plurality of stub fibers secured therein with ends of the fibers projecting beyond the end of the ferrule. The connector also includes first and second opposed splice members extending lengthwise from a first end proximate the end of the ferrule to an opposite second end, and the ends of the stub fibers extend between the opposed splice members at the first end thereof and are disposed in fiber-aligning grooves formed in the first splice member. The splice members are arranged with a fiber-receiving space therebetween to allow the optical fibers of the fiber optic ribbon to be inserted through the fiber-receiving space such that the optical fibers engage the grooves and are guided by the grooves into optically connected relation with the ends of the stub fibers. The connector further includes a cam movable between an initial position allowing the splice members to move apart to enlarge the fiber-receiving space to facilitate insertion of the optical fibers therein, and a final position in which the cam urges the splice members in the vicinity of the ends of the stub fibers toward each other to clamp the ribbon fibers therebetween. The rear end portion of the second splice member can pivot away from the first splice member to facilitate inserting the ribbon into the connector.

Wall Mountable Mixed Media Outlet

View page
US Patent:
6457874, Oct 1, 2002
Filed:
Aug 31, 2000
Appl. No.:
09/652287
Inventors:
Mark R. Dagley - Ft. Worth TX
Markus A. Giebel - Hickory NC
Kevin L. Morgan - Paradise TX
Mark D. Walters - Azle TX
Steven R. Baker - Ft. Worth TX
Assignee:
Corning Cable Systems LLC - Hickory NC
International Classification:
G02B 638
US Classification:
385 75, 439577
Abstract:
A mixed media outlet is provided that is capable of being mounted upon a wall and that includes ports that are typically designed to provide separate access to an electrical network and to an optical network. The wall mounted outlet can therefore permit a telephone to be connected to the electrical network, and a computer to be connected to the optical network. Alternatively, the outlet can permit a telephone to also be connected to either the same or a different optical network than the computer. The mixed media outlet includes a housing adapted to be wall mounted and first and second ports that are disposed within openings defined by the housing, such as a data port and a voice port. The mixed media outlet also includes an electro-optic converter connected to the first port for converting between electrical and optical signals such that electrical signals presented at the first port are converted to corresponding optical signals for transmission to an optical network and optical signals delivered by an optical fiber are converted to electrical signals for transmission via the first port to a computer, for example. The mixed media outlet can also include a fiber port for optically interfacing the optical fiber and the electro-optic converter in order to permit optical communication therebetween. While the fiber port can be in the same plane as the data and voice ports, the fiber port can lie in a different plane in some embodiments.

Windowless, Rectangular Ferrule In A Preassembled Multifiber Connector And Associated Assembly Method

Assignee:
Corning Cable Systems LLC - Hickory NC
International Classification:
G02B 638
US Classification:
385 78, 385 79, 385 76, 385 77
Abstract:
A preassembled multifiber connector is provided that includes a connector housing and a windowless multifiber ferrule that is substantially rectangular in lateral cross-section. The windowless multifiber ferrule can be at least partially disposed within an internal cavity defined by the connector housing to thereby form a multifiber connector that is free of optical fibers. Thus, the multifiber connector is capable of being preassembled prior to inserting the plurality of optical fibers into the optical fiber bores defined by the windowless multifiber ferrule. A corresponding method of preassembling a multifiber connector is therefore also provided according to the present invention. A ferrule is also provided that is capable of being selectively converted from a windowless configuration to a windowed configuration. The ferrule of this embodiment includes a ferrule body that not only defines at least one optical fiber bore, but that also defines a well extending through a side surface of the ferrule body. The ferrule body also includes a removable web at least partially covering the well to thereby define the windowless configuration of the ferrule.

Polarity Reversal For Fiber Optic Connections

View page
US Patent:
6634796, Oct 21, 2003
Filed:
Jun 30, 1999
Appl. No.:
09/343763
Inventors:
Michael de Jong - Fort Worth TX
Markus A. Giebel - Hickory NC
Thomas A. Church - Saginaw TX
Kevin L. Morgan - Paradise TX
James P. Luther - Hickory NC
Assignee:
Corning Cable Systems LLC - Hickory NC
International Classification:
G02B 638
US Classification:
385 56, 385 75, 385 76, 385139
Abstract:
Devices and methods are described that permit simple correction of a fiber optic polarity reversal problem. An adapter is described having receptacles to receive a connector on a first end, or user end, and on a second end, or contractor end. Both the receptacles provide keying arrangements so that the connectors can be received only when correctly oriented with respect to the adapter. The keying arrangement on the contractor end, however, is reversable so that the connector may be inserted in one of two predetermined orientations, at the behest of the contractor or installer. Adapters are also described that receive connectors only in a physically reversed orientation to counteract a reverse polarity condition. In addition, a jumper is described that can be interposed between a connector and adapter to correct a reverse polarity condition.
