ABSTRACT:
Disclosed is a method for producing carbon-coated optical fiber including the steps of thermally decomposing a halogenated hydrocarbon compound to obtain a thermal decomposate of the halogenated hydrocarbon, and depositing the thermal decomposate on a surface of an uncoated optical fiber to form at least one carbon coating layer on the surface of the fiber. The halogenated hydrocarbon compounds include CClF.sub.3 , CCl.sub.2 F.sub.2 , CCl.sub.3 F, C.sub.2 Cl.sub.2 F and C.sub.2 ClF.sub.5. The deposition is performed at a temperature which is slightly below the thermal decomposition temperature. The method includes an optional step of coating at least one resin layer over a surface of the carbon coating layer.
