In this paper

the impact of big-size perform high-speed drawing on optical fibers properties was introduced.A more in-depth study onφ120-200mm and 2000m/min high speed drawing technology-through equipment modification and process optimization.Through the optical fiber drawing furnace structure and annealed devices modification to optimize the drawing furnace heating profile and flow distribution

which greatly improved the optical fiber attenuation

curl

cladding circularity

cladding diameter variation and strength properties of big-size perform high-speed drawing.
