Abstract
PURPOSE: To continuously form a film round an optical fiber at a high speed by introducing inert gas into isolation chambers connecting to both ends of a reaction chamber; feeding reaction gases into the reaction chamber; heating them to induce chemical reaction; and contacting the reaction product to the optical fiber continuously passing through the reaction chamber in continuous coating of the fiber by a chemical vapor phase deposition method.
CONSTITUTION: Inert gas is introduced from inlets 18, 19 into isolation chambers 12, 16 isolating reaction chamber 14 from the surrounding air. Optical fiber 10 is continuously sent into chamber 12 chrough opening 11, coated in chamber 14 as follows, and drawn out through opening 15, chamber 16 and opening 17: reaction gases, e.g. NH3 and silane accompanied by carrier gas N2 are introduced into chamber 14 from inlet 20 and heated with heating coil 22 to induce chemical reaction, thereby forming a film of several ÅW1000Å or more in thickness on the surface of fiber 10.
