Beschreibung
Zusammenfassung:	In the process of drawing optical fibers, a protective plastic coating is applied to the fiber by applying a curable liquid coating material thereto and the subsequently curing the liquid coating to a protective plastic layer. At high fiber draw speeds, air entrained with the fiber enters the liquid coating material and causes bubbles in the cured coating. The incidence of bubbles in the coating is reduced by replacing air adjacent the fiber surface with helium.
