Abstract

PURPOSE: To form a uniformly thick protective coating layer by on-line operation, by passing a quartz glass optical fiber through a synthetic resin melt filled in a specified vessel.
CONSTITUTION: Preform 1 made of quartz glass is placed in a pot, pulled out of the tip while being heated and softened, passed between capstan rollers 3, and introduced into taper tube 4 containing silicone resin 5 for primary coating. After the primary coating the fiber is continuously passed through the melt of secondary coating synthetic resin 11, such as polyethylene filled in taper metallic vessel 9 with small opening 8 in the tip while resin 11 is being melted with heater 12. The thickness of secondary coating layer thus formed depends on the kind of resin and the diameter of opening 8, but not on the movement speed of the fiber. As a result, a uniform and high quality coated optical fiber to be obtained by a series of on-line operation ensuing spinning.
