摘要

Method for fabricau00c7u00e7o a prefilled form, as well as a method for formau00c7u00e7o fiber u00e0tica from such a prefilled form.The present invention relates to a method for manufacturing a preform for fiber attic through a process of depositing vapor.The conditions in which the plasma is created and in which the plasma is moved from side to side along the longitudinal axis of the tube hollow substrate between a point of inversion near the side of supply and a point of inversion near the side of the discharge tube hollow substrate.So that the location where the deposit of soot associated with a phase happens is axially spaced from the location where the deposit of soot associated with (s) and other (s) phase (s).
