Method For Reducing The Hydrogen Sensitivity Of Optical Fibers At 1380Nm-1410 Nm
US Patent:
6704485, Mar 9, 2004
Filed:
Aug 22, 2001
Appl. No.:
09/933662
Inventors:
Jean-Florent Campion - Conflans St Honorine, FR
Isabelle DeCaux - Mantes la Ville, FR
Philippe Dupont - Levallois Perret, FR
Terry Voots - Hickory NC

Assignee:
Alcatel - Paris
International Classification:
G02B 602
US Classification:
385123
Abstract:
A method for reducing the hydrogen aging loss of silica optical fibers by irreversible reaction of the peroxide defects with deuterium is described. This method comprises the step of contacting the optical fiber with deuterium by exposure to a gas mixture containing deuterium at a temperature compatible with the fiber without exposing the fiber to any further activation, and subsequently the step of degassing the fiber in a neutral atmosphere. The invention relates further to a process of producing optical fibers with low hydrogen aging loss wherein an optical fiber is treated using the method for reducing the hydrogen aging loss. Finally, the invention relates to optical fibers with low hydrogen aging loss obtainable by this process and telecommunication cables produced using these optical fibers. Using the new method, an activation step using intense light and/or elevated temperature is not necessary to achieve the reaction of peroxide defects in silica with deuterium. The process according to the invention allows reaction at temperatures such as the ambient temperature without any further activation.
Method And Apparatus For Controlling The Shape And Position Of A Deformable Object
US Patent:
2002005, May 9, 2002
Filed:
Oct 24, 2001
Appl. No.:
10/032896
Inventors:
Roger Charlton - Newton NC, US
Daniel Fletcher - Conover NC, US
Charles Giebner - Hickory NC, US
Daniel Fletcher - Conover NC, US
Charles Giebner - Hickory NC, US
International Classification:
C03B037/07
US Classification:
065/382000, 065/485000, 065/491000
Abstract:
A method and apparatus for controlling the shape and position of a deformable object are described. At least a portion of an object is heated to a temperature sufficient to render the heated portion deformable by a force. An image profile of the heated portion of the object is obtained. A controller compares the image profile to a reference profile and produces an error image signal. Based on the error image signal, an instruction signal is generated. A force applicator responsive to the instruction signal applies a radial force to at least one distinct predetermined location on the heated portion of the object in response to the instruction signal to cause the heated portion of the object to conform to the reference profile. The invention is particularly useful in controlling the shape of an optical fiber preform.
Process For Online Spheroidization Of Quartz And Silica Particles
US Patent:
2003007, Apr 17, 2003
Filed:
Oct 12, 2001
Appl. No.:
09/975508
Inventors:
Jacques Goudeau - Lyon Cedex, FR
Roger Charlton - Newton NC, US
Daniel Fletcher - Conover NC, US
Roger Charlton - Newton NC, US
Daniel Fletcher - Conover NC, US
Assignee:
ALCATEL
International Classification:
C03B037/018
US Classification:
065/413000
Abstract:
A preform overcladding device is provided. The preform overcladding device includes an injector for providing particles having a predetermined material, and a preheater for preheating the particles provided by the injector. The preform overcladding device also includes a heater for heating and depositing onto a preform the particles preheated by the preheater.
Single Mode Bend Insensitive Fiber For Use In Fiber Optic Guidance Applications
US Patent:
4838643, Jun 13, 1989
Filed:
Mar 23, 1988
Appl. No.:
7/171979
Inventors:
Leslie B. Hodges - Roanoke VA
Roger Charlton - Roanoke VA
James H. Bowen - Salem VA
Roger Charlton - Roanoke VA
James H. Bowen - Salem VA
Assignee:
Alcatel NA, Inc. - Claremont NC
International Classification:
G02B 622
US Classification:
350 9633
Abstract:
A double-clad single mode optical fiber with a depressed inner cladding exhibits increased resistance to attenuation increases resulting from small radius bends and lower attenuation sensitivity to temperature changes when the mode field diameter is less than 7 um and the ratio of the radius of the inner cladding to the radius of the core is at least 6. 5 to one.
