Process and device for coating glass fibers with a carbon layer and its use for optical fiber.

摘要

Process and device for depositing a layer of carbon on a glass fibre (11) by pyrolysis of a gas of hydrocarbon or halogenated hydrocarbon type, characterised in that, before being brought into contact with the said gas, the fibre is preheated in a furnace (4) to a temperature higher than that of the pyrolysis of this gas. <IMAGE>
