Spinning device for low polarization mode dispersion of optical fiber

摘要

Disclosed is a spinning device for low polarization mode dispersion. The spinning device for minimizing PMD(Polarization Mode Dispersion) of the drawn optical fiber in the optical fiber drawing process includes: a base plate arranged at a lower end of a drawing tower; a tilting spinning wheel mounted on the base plate for rotating along a first rotational shaft, for transferring a drawn optical fiber to a capstan, for periodically rotating along a second rotational shaft within a predetermined angle range at a perpendicular relation to the first rotational shaft, for applying a periodic twisting on the optical fiber using the tension of the drawn optical fiber with its outer periphery touched with the drawn optical fiber; and, a speed reducing unit connected to the second rotational shaft of the tilting spinning wheel for reducing the rotational speed of the wheel.
