ABSTRACT:
Optical fibres are manufactured by etching the inner wall of a tube. The tube wall is etched by passing a hydrogen-free fluorine compound through the tube while reciprocating a nonisothermal plasma through the tube. After etching, core glass is chemically deposited on the etched surface. The core glass is deposited from the gaseous phase while using a nonisothermal plasma for initiating the reaction. The inner-coated tube is then collapsed and drawn to form an optical fiber.
