摘要： Detectors detecting flashes caused by the escape of light from the surface of an optical fiber as it rapidly passes a detection point suitable for use in on-line detection of optical fiber flaws. A detector includes a plurality of view systems, each view system consisting of a spherical mirror (608), a plurality of lenses and a detector (616). Each spherical mirror (608) is placed at its radius of curvature from an optical fiber (618) to be tested for flaws. A first lens (610) of each view system is placed at its focal length away from the optical fiber (618), opposite the mirror. A second lens (612) of each view system is placed opposite the first lens (610). The detector (616) is placed at the focal length of the second lens (612) away from the second lens (612), opposite the first lens (610). Additional lenses may be placed between the first lens (610) and the second lens (612) of each view system. The use of multiple view systems reduces or eliminates the dead zone of the detection system. All of the above approaches may be employed to detect flaws as an optical fiber is rapidly moved past the detector. Flaws may be discriminated and recorded in real time providing improved quality control, and manufacturing process data.

摘要： A fiber preform (20) is contaminated with contaminates such as silicon nitride or silicon carbide. The preform is then held in a chamber (10) with a reducing gas (29) being introduced into the chamber. The reducing gas prevents the contaminates from being oxidized. If the contaminates were oxidized, the strengh of the final fiber would be reduced.

摘要： A method for forming an optical fiber includes drawing the optical fiber from a glass supply and treating the fiber by maintaining the optical fiber in a treatment zone wherein the fiber is cooled at a specified cooling rate. The optical fiber treatment reduces the tendency of the optical fiber to increase in attenuation due to Rayleigh scattering, and/or over time following formation of the optical fiber due to heat aging. Methods for producing optical fibers along nonlinear paths incorporating fluid bearings are also provided thereby allowing for increased vertical space for the fiber treatment zone.

摘要： A method for producing a coated optical fiber may include drawing an optical fiber from a draw furnace along a first vertical pathway. The optical fiber may then be routed through at least one fluid bearing thereby redirecting the optical fiber along a second vertical pathway. Thereafter, a thermoplastic coating may be applied to the optical fiber with a thermoplastic coating system. The optical fiber may then be wound onto a fiber storage spool with a fiber take-up system. The fiber take-up system may be space apart from the thermoplastic coating system such that the thermoplastic coating may be cooled before the optical fiber is wound onto the fiber storage spool.
