Abstract
A method and apparatus for cooling a glass optical fiber drawn from a glass preform, prior to applying a protective coating to the fiber, wherein the fiber is transported through a cooling zone containing coolant consisting of a solid or liquid dispersion of a condensible gas, the gas being a chemical element or compound having a vapor pressure of at least 1 atmosphere at 25.degree. C. such that rapid coolant vaporization at ambient temperatures is insured, are provided.
Claims8
A method for cooling a glass optical fiber as drawn from a glass preform to reduce the temperature thereof to a temperature in the range for coating the fiber which comprises the step of transporting the fiber through a cooling zone containing coolant consisting of a solid or liquid dispersion of a chemical element or compound having a vapor pressure of at least 1 atmosphere at 25.degree. C.
