摘要： A method and apparatus for manufacturing an optical fiber comprises the steps of and means for heating a glass rod, which is a first preform of the optical fiber, elongating the heated glass rod to generate a second preform, and further heating and drawing the second preform to a filament-like form to generate the optical fiber, wherein the elongation speed is controlled at a plurality of locations along the axial direction of the glass rod based on the diameter at the plurality of locations along the axial direction of the glass rod and the heating is controlled based on the average value of the diameter at the plurality of locations of the glass rod.
