    摘要: One embodiment of the disclosure relates to a method of cleaning silica-based soot or an article made of silica-based soot, the method comprising the step of treating silica-based soot or the article made of silica-based soot with at least one of the following compounds: (i) a mixture of CO and Cl2 in a carrier gas such that the total concentration of CO and Cl2 in the mixture is greater than 10% (by volume, in carrier gas) and the ratio of CO:Cl2 is between 0.25 and 5; (ii) CCl4 in a carrier gas, such that concentration CCl4 is greater than 1% (by volume, in carrier gas). Preferably, the treatment by CCl4 is performed at temperatures between 600° C., and 850° C. Preferably, the treatment with the CO and Cl mixture is performed at temperatures between 900° C. and 1200° C. The carrier gas may be, for example, He, Ar, N2, or the combination thereof.

    摘要: A method and apparatus for making an optical fiber preform. The apparatus has an outer wall and an inner wall. The outer wall surrounds the inner wall and the inner wall surrounds an inner cavity of the apparatus. A consolidated glass rod is deposited in the inner cavity after which particulate glass material, such as glass soot, is deposited in the inner cavity around the glass rod. A radially inward pressure is applied against the particulate glass material to pressurize the particulate glass material against the glass rod.
