The linear speed decreases as the number of intermediate guide rollers increases and as the path line becomes more complex. Conventional optical fiber drawing equipment has a limit of about 40 to 50 −/min. Since the steady-state drawing speed is much thicker than this, at 150 m/min or more, there is a drawback that a considerable amount of scrap fiber is generated between the steady-state speed and the reduced limit speed.
