  • Method and apparatus for manufacturing an optical fiber provided with a hermetic coating
    Patent number: 6029476
    Abstract: A method and apparatus for manufacturing optical fibers provided with hermetic coatings, wherein the bare fiber made from a heated preform advances through a stream of reactive gaseous medium which flows at a constant speed in the direction of advance of the fiber, which is then accelerated, and which is finally removed remote from the fiber by a stream of inert gas flowing in the opposite direction from the direction of the stream of reactive gaseous medium. Application is to manufacturing optical fibers for telecommunications.

  • Method of coating an optical fiber
    Patent number: 6022585
    Abstract: The invention relates to a method of coating an optical fiber, the method comprising the following steps: applying a polymerizable coating material to the surface of the optical fiber; and polymerizing said material to obtain a coating. In the method, the optical fiber prior to application of said material is raised to a value T determining the value T' of the temperature at which said material polymerizes.
