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.
