Patent number: 8265439Abstract: An optical fiber preform comprises a primary preform that includes at least one inner cladding and a central core deposited inside a fluorine doped silica tube. The fluorine doped silica tube has a cross section area that is no more than about 15 percent smaller than the cross section area of the primary preform. The optical fiber preform has a large capacity, may be manufactured at reduced cost, and may be drawn to produce an optical fiber having reduced transmission losses.Type: GrantFiled: April 12, 2010Date of Patent: September 11, 2012Assignee: Draka Comteq, B.V.Inventors: Cedric Gonnet, Elise Regnier, Frans Gooijer, Pascale Nouchi

Patent number: 8265440Abstract: A method for manufacturing an optical fiber preform includes the steps of depositing an inner cladding and a central core inside a fluorine doped silica tube and thereafter collapsing the silica tube to form a primary preform. The fluorine doped silica tube has a cross section area that is no more than about 15 percent smaller than the cross section area of the resulting primary preform. The present method facilitates reduced-cost manufacturing of a high-capacity optical fiber preform, which may be drawn to produce an optical fiber having reduced transmission losses.Type: GrantFiled: April 12, 2010Date of Patent: September 11, 2012Assignee: Draka Comteq, B.V.Inventors: Cedric Gonnet, Elise Regnier, Frans Gooijer, Pascale Nouchi
