Abstract

En glasspreform for en optisk fiber blir f lammeskjært med en oksy- hydrogenflamme mens glasspreformen er vertikalt opphengt og blir rotert, og mens enten glasspreformen eller flammen eller begge disse blir beveget i forhold til hverandre, slik at overflaten på glasspreformen blir utjevnet.
