Publication number: 20050163434Abstract: A method of applying spin to a coated optical fiber to be rotated on its longitudinal axis so that the optical fiber has an ultra-low PMD (Polarization Mode Dispersion) includes the steps of: guiding the coated optical fiber so as not to be deviated from a certain range off a drawing axis at a lower end of an optical fiber coating point; giving torque to the optical fiber by contacting the coated optical fiber with a driving roller which vibrates on the center of an axis substantially parallel to a drawing direction at a lower end of the guiding point; and adjusting an amplitude (A) of the driving roller and a distance (l) between the guiding point and the vibrating point so as to control an angle (?) between the vibrating optical and the drawing axis. This makes it possible to control a spin rate (spins/m) of the optical fiber generated by rotation.Type: ApplicationFiled: October 31, 2002Publication date: July 28, 2005Inventors: Young-Il Kwon, Sang-Joon Bae, Joon-Keun Lee, Myung-Ho Jang, Bong-Hoon Lee
