摘要： Method for overcladding an optical fiber preform with a given target diameter (D0) of the final preform includes providing a primary preform to be overcladded, and successively depositing first overcladding layers by projecting and vitrifying silica particles on the primary preform moving in relative translation with a plasma torch. Each first overcladding layer has a given uniform thickness (d) and is deposited at a given, constant silica particle flow rate and at a given, constant translation speed. The method also includes the detection of a preform diameter (D1) greater than a given threshold (S) and the deposition of a final overcladding layer having the remaining required thickness (D0−D1) at a constant silica particle flow rate and at a reduced translation speed. The inventive method enables a preform to be overcladded efficiently with improved yield and high quality.

摘要： The invention relates to a method for manufacturing a final optical fiber preform by overcladding, said method comprising the steps of providing a primary preform; positioning said primary preform within at least one tube, wherein the at least one tube partly covers the primary preform to create a zone to be overcladded, being an overclad zone, which overclad zone is located on the primary preform outside the at least one tube; injecting a gas into the annular space between the primary preform and the at least one tube under overpressure relative to the pressure outside the at least one tube; overcladding the primary preform in the overclad zone with an overcladding material using an overcladding device. The invention also relates to an apparatus for carrying out the method. The invention allows overcladding a primary preform at low cost while maximally limiting the incorporation of impurities into the silica overclad.

摘要： The invention relates to a method for welding one end of a primary preform and one end of a silica bar having different properties. The method includes the steps of projecting and fusing silica grain under a plasma torch onto an end of the primary preform and an end of the silica bar, and bringing into contact these respective ends to form an excellent weld between the primary preform and the silica bar. The invention provides a cost-effective way to secure a primary preform to a glass-working lathe support while reducing the risk of costly preform breakage.
