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.

Ferrule For Facilitating Fiber-To-Fiber Contact And Associated Fabrication Method

View page
US Patent:
6416236, Jul 9, 2002
Filed:
Sep 7, 1999
Appl. No.:
09/390482
Inventors:
Darrell R. Childers - Hickory NC
James P. Luther - Hickory NC
Dennis M. Knecht - Hickory NC
Thomas Theuerkorn - Hickory NC
Assignee:
Siecor Operations, LLC - Hickory NC
International Classification:
G02B 636
US Classification:
385 84
Abstract:
A ferrule and an associated fabrication method are provided that facilitates fiber-to-fiber contact without requiring the end portions of the optical fibers to protrude beyond the front face of the ferrule. The ferrule includes a ferrule body having opposed front and rear faces and defining at least one optical fiber bore extending between the front and rear faces and adapted to receive an optical fiber. Advantageously, at least the medial portion of the front face through which the optical fiber bores open protrudes outwardly beyond at least some peripheral portions of the front face. By designing the front face such that the medial portion protrudes outwardly beyond peripheral portions of the front face, angular errors in the peripheral portions of the front face and dirt or other particles that accumulate on the peripheral portions of the front face will not prevent the medial portions of the front faces of a pair of ferrules from making contacting as the respective fiber optic connectors are mated. As such, the end portions of the optical fibers need not protrude much, if any, beyond the front face of the ferrule in order to establish fiber-to-fiber contact such that the ferrule can absorb at least some of the forces that would otherwise be imparted to the optical fibers.

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

View page
US Patent:
6499887, Dec 31, 2002
Filed:
Dec 31, 2001
Appl. No.:
10/039372
Inventors:
James P. Luther - Hickory NC
Joel C. Rosson - Hickory NC
Markus A. Giebel - Hickory NC
Karl M. Wagner - Hickory NC
Thomas Theuerkorn - Hickory NC
Dennis M. Knecht - Hickory NC
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.

Translucent Dust Cap And Associated Method For Testing The Continuity Of An Optical Fiber Jumper

View page
US Patent:
6554485, Apr 29, 2003
Filed:
Sep 11, 2000
Appl. No.:
09/658355
Inventors:
John W. Beatty - Newton NC
Dennis M. Knecht - Hickory NC
James R. Merriken - Hudson NC
Assignee:
Corning Cable Systems LLC - Hickory NC
International Classification:
G02B 638
US Classification:
385 72, 385 70
Abstract:
A dust cap is provided that includes a translucent end member that permits optical communication while the dust cap remains mounted upon a ferrule. The dust cap includes a sleeve having an open first end and an opposed second end that is closed by the translucent end member. The end member can also include a lens to facilitate optical communication. A medial portion of the sleeve can also define an internal chamfer that extends radially inward for engaging the ferrule such that the front face of the ferrule is spaced from the second end of the sleeve, thereby preventing contaminants from being transferred from the second end of the sleeve to the polished front face of the ferrule. The dust cap can also define a groove extending lengthwise through only a portion of the sleeve, i. e. , from the first end of the sleeve to a medial portion of the sleeve. The groove therefore permits air to vent from the bore while the dust cap is being mounted upon the ferrule, while isolating the front face of the ferrule from the external environment once the dust cap has been fully mounted, thereby protecting the polished front face of the ferrule from contaminants that may enter the groove.

Method And Apparatus For Positioning An Optical Fiber

View page
US Patent:
6672772, Jan 6, 2004
Filed:
Oct 31, 2001
Appl. No.:
10/003334
Inventors:
Brian J. Gimbel - Horseheads NY
James P. Luther - Hickory NC
Thomas Theuerkorn - Hickory NC
Hieu V. Tran - Charlotte NC
Darrell Childers - Hickory NC
Dennis M. Knecht - Hickory NC
Assignee:
Corning Cable Systems LLC - Hickory NC
International Classification:
G02B 636
US Classification:
385 60
Abstract:
Eccentricity of a optical fiber installed in a passageway of a ferrule is minimized by imposing a force on the end of the optical fiber projecting from the passageway at the ferrule end face to push the optical fiber to a desired position in the passageway, prior to curing an adhesive used for fixing the optical fiber in the passageway, so as to compensate for eccentricity of the passageway. In one embodiment, the force is imposed on the optical fiber by hanging a weight on the optical fiber. In another embodiment, the force is imposed on the optical fiber by using a pressurized jet of fluid. The point of application of the force, the magnitude of the force, and the viscosity of the adhesive are selected such that minimal optical fiber bending occurs, thereby assuring that the optical fiber is positioned at the desired position in the passageway for an appreciable distance from the ferrule end face along the passageway.

Low-Loss Intermatable Ferrules For Optical Fibers And A Method Of Fabrication Thereof

View page
US Patent:
6742936, Jun 1, 2004
Filed:
Nov 6, 2000
Appl. No.:
09/706913
Inventors:
Dennis M. Knecht - Hickory NC
James P. Luther - Hickory NC
Otto I. Szentesi - Hickory NC
Assignee:
Corning Cable Systems LLC - Hickory NC
International Classification:
G02B 638
US Classification:
385 67, 385 52
Abstract:
A method for assembling a population of ferrules to minimize the eccentricity of the fibers typically includes the steps of selecting a set of ferrules, determining the eccentricity of the ferrules, selecting a fiber, inserting the fiber within the ferrule bore, orienting the fiber within the ferrule, and securing the fiber in place. The result is a population of ferrules that can be mated with little or no insertion loss.
