OPTICAL FIBER WITH LOW PMD AND METHOD OF MAKING IT BY SPINNING

摘要

An optical fiber, and a method of making such optical fiber, wherein the optical fiber exhibits a beatlength greater than about 0.5 meters, and the fiber is spun to provide a polarization mode dispersion in the spun state of said fiber which is less than 0.05 ps/km1/2. The fiber is spun by employing a spin having a spin repeat distance of at least 1 meter and a plurality of varying spin reversal distances occurring within the spin repeat distance. The spin alternates between clockwise and counterclockwise directions.
