Abstract

Et porøst glassemne for en optisk fiber utsettes for fluordopende og forglassende behandling. Glassemnet ledes ved en høy temperatur og under en atmosfære som omfatter en fluorforbindelsesgass og en inert gass, gjennom et muffelrør som har et SiC-lag i det minste på dets innvendige overflate. Det anvendes en atmosfære som omfatter en gass valgt fra gruppen bestående av SiF4, CF4 og C2F6, og minste en gass valgt fra gruppen bestående av Si2F6 og Si3Fe.A porous glass blank for an optical fiber is subjected to fluorine doping and vitrification treatment. The glass blank is passed at a high temperature and under an atmosphere comprising a fluorine compound gas and an inert gas, through a muffle tube having a SiC layer at least on its inner surface. An atmosphere is used which comprises a gas selected from the group consisting of SiF4, CF4 and C2F6, and at least one gas selected from the group consisting of Si2F6 and Si3Fe.
