Patent abstract
An anti-PMD system comprises a pulley which oscillates in rotation and applies a torsion torque alternately in the clockwise direction and in the counterclockwise direction to an optical fiber during drawing of the optical fiber to reduce its PMD. A portion of a peripheral external surface of the pulley intended to be in contact with the optical fiber during drawing is convex.
