Abstract
A fiber (106) having low polarization mode dispersion is made by heating the end of a preform (100) with a furnace (101). The fiber is drawn from the heated end. The fiber passes between two rollers (102, 104). As the fiber passes therebetween, the angular tilt of each of the rollers is changed so that a spin is imparted to the fiber.
