Abstract
A surface of an optical fiber is coated by a method for coating a surface of an optical fiber with carbon comprising steps of introducing an optical fiber in a reaction chamber in the same direction as the flow of a coating raw material comprising carbon, hydrogen and halogen atoms and depositing on the surface of the optical fiber a carbon layer formed from the raw material by chemical vapor deposition, whereby the coated optical fiber has improved initial tensile strength and absorbs less hydrogen.
