Abstract:
    A method of manufacturing a glass fiber preform in which a quartz glass rod having an outer coating containing chlorine and a core doped for higher refractive index has blown thereon a soot formed by a burner fed with quartz glass raw material and a chlorine group gas undergoing flame hydrolysis. The resulting composite is the heated and fused to collapse.
