Filed:

Appl. No.:

09/395043

Inventors:

Terry M. Sanderson - Tucson AZ
John Michael Turnipseed - Lilburn GA

Assignee:

Fitel USA Corp. - Norcross GA

International Classification:

G06F 1900

US Classification:

700122, 4271632

Abstract:

The present invention provides a method and apparatus for monitoring a UV curing lamp system to determine whether a UV-curable material passing through the curing lamp system is being properly cured. A thermal sensor is disposed to measure the temperature of gas being exhausted from a center tube of the UV curing lamp system. The center tube typically has nitrogen gas pumped into it to purge air from the center tube. The UV-curable material passes through the center tube. If a defect exists in the center tube, or if insufficient UV radiation is reaching the UV-curable material, the temperature of the gas stream exhausted from the center tube will drop. The temperature of the gas is compared to first and second threshold values, respectively, to determine whether a defect in the center tube exists or whether insufficient radiation is reaching the UV-curable material, respectively.

US Classification:

4271632, 427286, 4274071, 118125, 118255, 385128

Abstract:

A coated fiber strand including at least one heterogeneous region present in one or more coating layers. The heterogeneous region(s) preferably comprises a material useful for coding of the fiber. The optical fiber can include a primary coating layer and a secondary coating layer where the heterogeneous region(s) defines one or more colored stripes in or on the secondary coating layer. A method for forming a coated fiber, such as an optical fiber, includes introducing at least one coating layer onto a fiber strand such that one or more coating layers cover a portion of the surface of the strand. At least one heterogeneous region is introduced into or onto one or more coating layers, and the strand is cured to provide a desired product. A desired functionality, e. g. , coding, can thus be introduced onto a fiber without adversely effecting subsequent processing steps, e. g.

International Classification:

B32B 37/00

US Classification:

4271632, 156166, 156180, 427162, 4274342, 4274346, 4274347

Abstract:

The specification describes optical fiber cables designed for microduct installations. The microduct cables are coated with a sheath having particulates added to modify the drag of the outer surface of the cable to air, and thereby facilitate air blown installation. The particulates are nanoclay, silica, alumina, or other suitable solid particles of less than 5 microns. The coating comprises a prepolymer containing the filler, and is UV cured.

International Classification:

B05C 3/12

US Classification:

118420, 118125, 118683

Abstract:

Embodiments of the invention include a system and method for color-coating an optical fiber. The system includes a flow controller that controllably delivers and mixes color concentrate from one or more color concentrate reservoirs with a coating material, which colored coating material is fed to a coating die through which optical fiber passes. The color concentrate reservoirs are more compact and can be made portable along with the flow controller. Thus, the entire color coating system can travel to any appropriate location in the fiber manufacturing facility, e. g. , at any one of a number of draw towers. Such portability allows many different colors to be used at the same draw tower much more easily than conventional arrangements, which typically only have one color line per draw tower. The method includes providing an optical fiber, controllably delivering color concentrate with a coating material to a coating die, coating the optical fiber with the coating die, and curing the coated fiber.

B05D001/36

US Classification:

385/103000, 427/162000, 427/402000

Abstract:

The present invention provides coating methods for use in the manufacture of coated optical fibers. The coating methods of the present invention coat an optical fiber with a primary coating material that has a non-reactive colorant. A secondary coating material is applied over the primary coating material. The primary coating material may either be cured prior to application of the secondary coating material or both the primary and secondary coating materials may be cured at the same time to create primary and secondary coating layers over the optical fiber. In one embodiment, the secondary layer is formed of a substantially transparent material, visibly exposing the colored primary coating layer for inspection and/or measurement. The present invention further provides coated optical fibers made according to the coating methods of the present invention.
