    Short description: Drawing optical fiber

    A drawing tower produces a fine filament by heating the tip of a preform to melting temperature and pulling a strand of molten material downward.[1] Industrial drawing towers range in height from 30 to 45 meters. A drawing tower is used in the production of fiber optic communication cables. The preform is a multi-layered cylinder typically 20 cm in diameter, and 2 m long.[2]
