Publication number: 20220404571Abstract: In curing a matrix material of a rollable optical fiber ribbon, ultraviolet light may be concentrated in a selected range of wavelengths to avoid further curing the primary coating of each fiber. A ribbon may be made by aligning the fibers, each having at least a primary coating, into a ribbon shape, applying a matrix material in intermittently distributed portions along the ribbon-shaped group of fibers, and exposing the ribbon-shaped group of fibers and applied matrix material to ultraviolet light concentrated in a range of wavelengths absorbed more by the matrix material than by the primary coating.Type: ApplicationFiled: November 5, 2019Publication date: December 22, 2022Applicant: OFS Fitel, LLCInventors: Harry D Garner, Kariofilis Konstadinidis, Heng Ly

Patent number: 10486194Abstract: Post-draw tower coating curing provides additional curing to an optical fiber coating after the fiber exits the bottom or output end of an optical fiber draw tower. A system may include a draw tower and a coating curing unit. The draw tower has at least one coating applicator. The coating curing unit may be located along a fiber path between the output end of the draw tower and a fiber takeup system.Type: GrantFiled: December 11, 2017Date of Patent: November 26, 2019Assignee: OFS FITEL, LLCInventors: Harry D Garner, Douglas Edward Horgen, Kariofilis Konstadinidis

Publication number: 20140205251Abstract: The specification describes an optical fiber color coding scheme that uses two colors, where each of the two colors constitutes one half of the surface of the optical fiber coating. If a longitudinal portion of the coating is considered a hollow cylinder, then each of the two colors is a hollow hemi-cylinder. To ensure that each of the two colors is always plainly visible to an installer, the two colors are formed with a twist. Using two colors for coding substantially increases the number of available unique color codes. Coloring the entire coating reduces the chances of error in identifying the optical fibers.Type: ApplicationFiled: January 22, 2013Publication date: July 24, 2014Applicant: OFS FITEL, LLCInventors: Harry D. Garner, Jonathan M. Jobe, Kariofilis Konstadinidis

Patent number: 6937325Abstract: A method and an apparatus for obtaining measurements of eccentricity in optical fibers, from which the spin imparted to the optical fiber can be ascertained. The method and apparatus enable eccentricity to be measured in such a way that this measurement can be utilized to determine the amount of spin imparted to an optical fiber as the optical fiber was being drawn, although the eccentricity measurement may be used for purposes other than to determine the amount of spin in the fiber. By viewing the fiber from one or more positions along the length of the fiber, the eccentricity of the fiber as a function of position along the length of the fiber can be determined. The amount of spin in the fiber can then be determined from the eccentricity measurement.Type: GrantFiled: January 30, 2003Date of Patent: August 30, 2005Assignee: Fitel U.S.A. CorporationInventors: Andrew Ingles, Jr., Albert Ritger, Zhi Zhou, Harry D. Garner

Patent number: 6927849Abstract: A monitoring system for detection of defects in an optical fiber coating during production of the fiber has first and second beam generating means which produce planar coherent beams which cross each other at the fiber passing through the system creating one or more diffraction patterns. A first plurality of photodetectors are mounted in a mount, the front face of which is impinged by the planar diffraction pattern, and a second plurality of photodetectors is similarly mounted in position below the impinging pattern. A defect in the fiber coating, regardless of shape or orientation, will cause the pattern or patterns to be tilted or shifted upward, downward, or planarly tilted to impinge one or more of the photodiodes which, as a result, generates a signal which is applied to a comparator and control circuit.Type: GrantFiled: October 23, 2002Date of Patent: August 9, 2005Assignee: Furukawa Electric North America, Inc.Inventors: Ronald L. Adams, Harry D. Garner, Robert Thornton
