Abstract
A method of cooling an optical fiber during drawing through contact with at least one cooling fluid in at least one cooling area, wherein fast cooling, i.e. cooling that is faster than cooling in the surrounding air, from an initial temperature of the fiber to a temperature at the end of fast cooling of said fiber, is followed by slow cooling, i.e. cooling slower than cooling in the surrounding air, from a temperature of said fiber at the start of slow cooling to a temperature of said fiber at the end of slow cooling.
