Abstract

Disclosed is a method for fabricating an optical fiber preform. The method includes: (a) growing a first soot preform on a starting member along a lengthwise direction of the starting member by a soot deposition; (b) dehydrating the first soot preform; (c) sintering the dehydrated first soot preform, to obtain a first glassed optical preform; and (d) elongating the first optical fiber preform by heating the first optical fiber with a heat source that excludes hydrogen, wherein the first glassed optical fiber is elongated by means of only a heat source that excludes the use of hydrogen.

Description

technical field [0001] The present invention relates to optical fiber preforms, and more particularly, the present invention relates to methods of making optical fiber preforms using soot deposition and methods of making low water peak optical fibers. Background technique [0002] Known methods of fabricating optical fiber preforms include Modified Chemical Vapor Deposition (MCVD), Vapor Axial Deposition (VAD), Outside Vapor Deposition (OVD), Plasma Chemical Vapor Deposition (PCVD), and the like. [0003] In the vapor phase axial deposition method, source materials, fuel gas, and the like are supplied to a burner, whereby soot is generated by flame hydrolysis. The resulting soot is then deposited on the starting components. The soot preform further grows from the end of the starting member along the longitudinal direction of the starting member. [0004] Fig. 1 is a flowchart illustrating a conventional manufacturing method of an optical fiber preform. The method includes...
