An apparatus for curing a coating composition disposed on a glass optical fiber. The apparatus includes a reflector, the reflector having an interior surface delineating a boundary of a cavity, the interior surface including a plurality of portions, each of the portions extending along a different curved contour. Furthermore, each of the plurality of portions is configured to reflect curing light so that the reflected curing light is concentrated to a curing zone within the cavity such that all the reflected curing light within the curing zone has an intensity of about 60% or greater relative to a maximum intensity of the reflected curing light. A fiber location for the glass optical fiber is located within the curing zone. Additionally, the plurality of portions includes at least a first portion and a second portion, the first portion having a different degree of curvature than the second portion.

Reflector for curing optical fibers and methods of using the same

An optical fiber production system includes an annealing furnace having a furnace inlet, a furnace outlet, and a process tube extending between the furnace inlet and the furnace outlet, the process tube having a process tube wall and a heating zone including at least one heating element. The optical fiber production system also includes a gas distribution assembly fluidly coupled to the furnace outlet and structurally configured to induce gas flow from the gas distribution assembly into the process tube such that gas flows within the process tube in an upflow direction.

Methods and systems for controlling air flow through an annealing furnace during optical fiber production

An optical fiber and its manufacture are provided. The optical fiber includes an optical waveguide and a cured primary coating layer surrounding the optical waveguide. The optical fiber further includes a cured secondary coating layer surrounding the cured primary coating layer. The optical fiber further includes a cured tertiary ink coating layer surrounding the cured secondary coating layer. The cured tertiary ink coating layer has a glass transition temperature (T) of greater than or equal to 75&#xb0; C.

Method of applying an ink layer onto an optical fiber

An apparatus and method for coating an optical wave guide fiber with a liquid polymer coating includes pressurizing a chamber with a process fluid and venting the process fluid along, and in a direction opposite the direction of travel of, the incoming fiber, to strip particles from the incoming fiber before the particles enter the die assembly.
