APPARATUS AND METHOD FOR REDUCING BREAK SOURCES IN DRAWN FIBERS
摘要
A glass preform (30) for making optical waveguides has surface impurities such as silicon carbide or silicon nitride. The preform is drawn in a furnace (12) that is supplied with oxygen via a conduit (40). The oxygen causes the impurities to oxidize and not effect the strength of the fiber.
