    摘要: The optical fiber comprises: (a) a core having a refractive index profile and a centerline; and (b) a cladding layer surrounding and directly adjacent the core; wherein core includes updoping material and is doped with F in at least one region of the core, such that either: (a) the average longitudinal acoustic wave velocity within the core is within 0.05% of the longitudinal acoustic wave velocity within the cladding; or (b) the longitudinal acoustic wave velocity at one region of the core is different from the longitudinal velocity at another region of the core by at least 0.2%.

    摘要: 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.
