ABSTRACT:
A method for producing low-PMD fiber, in which a glass fiber is drawn from an optical fiber perform by a tractor which pulls such optical fiber from said perform; subsequent to said tractor pulling the fiber is twisted about its axis to increase the magnitude of twist which is imparted to said fiber. The fiber is then wound onto a fiber storage spool such that at least a portion of the twist imparted to said optical fiber is retained while said fiber is wound on said spool.
