Abstract

PURPOSE:By using low-voltage plasma formed by high-frequency electricity in the reactor of quartz tube, are formed the core part and it is spun from the inner pot of the double pot, thus producing title fiber mainly consisting of silica in high productivity. CONSTITUTION:Oxygen gas from opening 2, silicon tetrachloride and a variety of dopants of chlorides from inlet 3 are mixed and fed along with a carrier gas of argon or oxygen. Meanwhile, a vapor of zinc, cadmium, tin or lead is introduced from metal pool 5 through inlet 4 into vessel 1 using argon as a carrier gas. Low voltage plasma 7 is generated in the reaction part by induction coil 6 to form glass 8 with uniform composition. The glass formed is extruded from inner pot 14 of double pot 10 and simultaneously crushed glass material is molten in the outer pot 13 and extruded to form optical fiber 11. The inside of the vessel is kept under reduced pressure by exhausting the air from the bottom of quartz vessel 1.
