| titleOfInvention | A method for manufacturing a precursor for a primary preform for optical fibres by means of a plasma deposition process |
| abstract | The present invention relates to a method for producing a precursor. In other words, the present invention relates to a method of producing a precursor for a primary preform for an optical fiber by an inner plasma deposition process, the method comprising: providing a hollow substrate tube having a supply side and a discharge side; Causing the deposition of non-vitreous silica layers on at least a portion of the inner surface of the substrate tube at or near the reversal point of the discharge side to provide a substrate tube having non-vitreous layers on at least a portion of its inner surface Generating a first plasma reaction zone having first reaction conditions inside the hollow substrate tube by the hazardous electromagnetic radiation; And subsequently to deposition of the glassy silica layers on the substrate tube having non-vitreous layers on at least a portion of its inner surface to obtain a substrate tube on which the non-vitreous and glassy silica layers are deposited Creating a second plasma reaction zone having second reaction conditions inside the hollow substrate tube; And cooling the substrate tube to which the non-vitreous and glassy silica layers have been deposited to obtain the precursor for the primary preform. |
