Method And Apparatus For Clamping A Spinning Preform And Reducing The Vibration of Twisted Optical Fiber From A Spinning Preform

摘要

An apparatus for manufacturing an optical fiber is provided. The apparatus includes a spindle having a bore for receiving a preform of the optical fiber along a longitudinal axis defined by the spindle. A plurality of work holding devices are positioned apart from each other along the longitudinal axis of the spindle and configured to secure the preform against the spindle at two or more distinct positions when the preform is spinning. The plurality of work holding devices comprises any combination of chucks, collets, cams, set screws, or shims. A position of at least one of the work holding device is adjustable to shift the preform away from the longitudinal axis.
