  • Controlling the drawing rollers to produce diameter perturbations in an optical waveguide
    Patent number: 4163370
    Abstract: An optical waveguide having variations in diameter is produced by controlling the drawing rollers. Predetermined diameter variations along the length of an optical waveguide reduce dispersion in multimode waveguides. These diameter variations are produced by varying the rotational speed of the pulling rollers, by varying the diameter of the pulling rollers, by moving the pulling rollers axially or by moving a tensioning roller during the drawing process.
