摘要：
The subject of the invention is a method for manufacturing a final optical fiber preform via overcladding of a primary preform having a cross section area, the method comprising at least one manufacturing step of the primary preform by deposit of an inner cladding and of a central core inside a tube of Fluorine-doped silica, the tube being chosen such that it has a cross section area that is maximally 15 % less than the cross section area of the primary preform.
With the method of the invention it is possible to manufacture a preform of large capacity at reduced cost which allows the drawing of an optical fiber having reduced transmission losses.
