Abstract
A method for forming an optical fiber preform is provided. The method includes inserting a glass core cane into a glass sleeve such that the glass sleeve surrounds a portion of the glass core cane and such that there is a gap between the glass sleeve and the portion of the glass core cane surrounded by the glass sleeve. The method further includes depositing silica soot onto at least a portion of the glass core cane and at least a portion of the glass sleeve to form a silica soot preform, and flowing gas through the gap during processing of the silica soot preform.
