Abstract
PURPOSE:To effectively protect the surface of the titled fiber without injuring the optical characteristic of the titled optical fiber by forming a coating layer of a material constituted of an amorphous or a fine crystal contg. a carbon and a hydrogen atoms as a main component, at about room temp. CONSTITUTION:The coating layer 13 composed of at least the amorphous or the fine crystal having the property near to a diamond crystal, is formed on the surface of a clad 12 of the titled fiber 1 constituted of prescribed material and structure in the presence of a mixed gas of a hydrocarbon and a hydrogen gas by a low pressure vapor forming method such as a plasma CVD method, etc. As the coating layer is deposited on the surface of the clad at a room temp. - 150 deg.C, the titled fiber is protected with the coating layer which has the excellent hardness, abrasion resistance and antichemical property, etc., without receiving degeneration caused by heat, and maintaining the optical characteristics.
