Title (EN) IMPROVED OPTICAL FIBER FABRICATION PROCESS
(FR) PROCEDE DE FABRICATION DE FIBRES OPTIQUES AMELIOREES
Abstract: front page image
(EN)Method of fabricating glass fiber optical transmission lines. In accordance with the invention, an intermediate preform structure with a core-to-clad ratio greater than that desired in the ultimate fiber is obtained by depositing the core by means of a MCVD process, prior to the completion of the cladding. Subsequent to internal core deposition, additional material is added externally to complete the cladding thereby yielding an optical fiber preform with the desired core-to-clad ratio.
(FR)Methode de fabrication de lignes de transmission optique en fibres de verre. Une structure preformee intermediaire ayant un rapport noyau/revetement superieur a celui que l"on trouve dans la derniere fibre est obtenue en effectuant le depot du noyau par une methode MCVD avant d"avoir acheve le revetement. Apres depot du noyau interne, du materiau supplementaire est ajoute exterieurement pour terminer le revetement produisant de la sorte une preforme de fibre optique avec le rapport desire noyau/revetement.
