Appl. No.:

10/328092

Inventors:

Heather Boek - Corning NY, US
Carl Ponader - Beaver Dams NY, US

International Classification:

C03B037/018

US Classification:

065/398000, 065/397000, 065/412000, 065/413000

Abstract:

A method of forming an optical fiber by heat treating a consolidated glass article, doped with at least one refractive index-modifying dopant, at a temperature between about 1100 C. and 1400 C. and for a time between about 1 hour and 12 hours in a helium-containing atmosphere. The consolidated glass article is an optical fiber precursor. The optical fiber drawn from the heat treated consolidated glass article exhibits an attenuation lower than an optical fiber drawn from a substantially identical optical fiber precursor that has not been heat treated in accordance with the present invention.

International Classification:

H04B 10/2507
C03B 37/012
G01B 11/08
G01B 11/25
G02B 6/02

Abstract:

An apparatus for producing large glass preforms with minimal clad to-core waveguide distortion from a glass body having a weight, an outer surface, core rods, and a cladding surrounding and separated from the core rods by a gap. The apparatus includes collars affixed to the top and bottom of the cladding; a spacer upon which the core rods rest; a first unit holding and supporting both the bottom collar and the spacer; a second unit holding and supporting the top collar; and a frame defining a heating zone having a heating element to heat the glass body. The weight of the glass body above and below the molten glass in the heating zone is supported by the first and second units without contacting the outer surface of the glass body.

Inventors:

- Buford GA, US
Carl W. Ponader - Buford GA, US

International Classification:

C03B 37/029

Abstract:

A variable seal for shielding from contaminants both an object to be heated in, and the heating element of, a high-temperature furnace. The seal has a first support ring and a second support ring separated by a distance. One or more components control the distance between the two support rings. A high-temperature fabric cylinder is attached to the support rings, is located where the object enters or exits the furnace, and surrounds at least a portion of the object. A mechanism engages the approximate center of the fabric cylinder to close the fabric cylinder as the one or more components decrease the distance between the two support rings and to open the fabric cylinder as the one or more components increase the distance between the two support rings, whereby the fabric cylinder continuously contacts the circumference of the object regardless of the diameter of the object.

Abstract:

An apparatus and related process for producing large glass preforms with minimal clad to-core waveguide distortion from a glass body having a weight, an outer surface, core rods, and a cladding surrounding and separated from the core rods by a gap. The apparatus includes collars affixed to the top and bottom of the cladding; a spacer upon which the core rods rest; a first unit holding and supporting both the bottom collar and the spacer; a second unit holding and supporting the top collar; and a frame defining a heating zone having a heating element to heat the glass body.
