METHOD FOR FORMING OPTICAL FIBER AND PREFORMS

摘要

A method of forming an optical fiber includes the steps of forming a silica-based soot blank with at least one silica-based soot core cane at least partially embedded in the soot blank. The soot blank with the soot core cane positioned therein is consolidated to form a preform. The preform is then drawn to form an optical fiber. The soot core cane preferably has an average bulk density within 10% of the bulk density of the soot blank, and more preferably within 5% of the bulk density of the soot blank.
