ABSTRACT:
Disclosed is an optical waveguide fiber having a reduced PMD and a method of making the optical waveguide fiber. The optical waveguide fiber in accord with the invention has a particular spin pattern impressed upon the optical waveguide fiber during the drawing step. The spin pattern causes the fast axis of birefringence to rotate along the long axis of the optical waveguide fiber. The spin functions in accord with the invention provide for reduced PMD even in cases in which draw speed, spin magnitude, or modulation parameter vary while the spin pattern is being impressed upon the optical waveguide fiber.
