ABSTRACT:
A method of manufacturing optical fibers by applying to a substantially cylindrical thin glass member layers of porous glass having a radially varying composition by means of pulverized glass generators. The porous glass layers are heated and defoamed to form a transparent glass preform containing the thin glass member which preform is heated and drawn to reduce the cross-sectional area to form an optical fiber.
