Abstract

Disclosed is an optical fiber cooling apparatus and method used in an optical fiber drawing process, which measures an outer diameter of a coated optical fiber indicating its coating condition and controls a feeding amount and a recovery amount of a coolant depending on the outer diameter, thereby ensuring uniform coating of the optical fiber, and which can reduce a usage amount of the coolant used to cool an optical fiber by increasing a recovery amount of the coolant even though the coolant was fed in small quantities, and of which configuration is simple, resulting in reduced facility cost.
