The influence of the drawing process in optical fibers on the radiation resistance property was investigated. The ESR spectra for the optical fibers drawn under various conditions were measured at room temperature (R.T.) or 77 K. The fibers were drawn at three different temperatures (high, medium and low) and the drawing velocity was kept constant. The drawing defects were abundantly detected at R.T. in the sample drawn at high temperature. Many non-bridging oxygen hole centers (NBOHC) induced during the drawing process were observed at 77 K. The formation of NBOHC was also discussed.
