ABSTRACT:
A stable secondary coating, for example of nylon, is applied to a primary coated optical fiber by a process including high-speed (.gtoreq.100 meters per minute) extrusion of the secondary coating material, cooling of the extruded material by quenching in cold water at a position up to four meters from the extruder crosshead, and subsequent annealing to increase the density of the extruded and quenched material.
