Description

technical field [0001] The optical fiber drawing cooling system of the invention relates to a bare fiber cooling system in the single-mode optical fiber drawing process, which is used for reducing the temperature of the optical fiber before coating, and is suitable for improving the curing performance of the optical fiber. An optical fiber drawing cooling system that makes single-mode optical fiber suitable for high-speed, large-capacity, and long-distance optical fiber communication systems. Background technique [0002] In the whole production process of optical fiber, the first step is to melt the optical fiber preform: the optical fiber preform is placed in the heating furnace of the wire drawing device, and after melting into a fluid state, it is cooled, coated and solidified, and then the wire is taken up. , become a semi-finished fiber. When the optical fiber is just out of the furnace, the temperature is high, and the prerequisite for optical fiber coating protectio...
