Abstract: PROBLEM TO BE SOLVED: To reduce attenuation of a glass optical fiber due to heat aging and Rayleigh scattering in a heat treatment of the fiber. SOLUTION: In the method for forming an optical fiber, the optical fiber is formed by drawing at ≥10 m/sec draw rate from a heated glass source (block 10) and is heat-treated by maintaining the optical fiber within a heated treatment zone for the total resident time of 0.07-0.25 sec, while subjecting the optical fiber to an average cooling rate of 1,200-5,000 °C/sec defined by ä[fiber surface temperature in an inlet zone]-[fiber surface temperature in the outlet zone]}/[the total resident time of the optical fiber in the treatment zone] (block 20).

Abstract: A method for forming a doped optical fiber includes drawing the optical fiber from a doped glass supply at a draw speed and a draw tension sufficient to introduce a heat aging defect in the optical fiber. The optical fiber is treated by maintaining the optical fiber within a treatment temperature range for a treatment time while preferably maintaining the optical fiber within a treatment tension range to reduce the tendency of the optical fiber to increase in attenuation over time following formation of the optical fiber. Apparatus are also provided.
