LOW PERMEABILITY GAS RECYCLING IN CONSOLIDATION |
摘要 |
<p>Methods for recycling a low permeability gas such as krypton in the consolidation process of optical fiber manufacturing. The low permeability gas is sent to a purification unit or plant before being reutilized in the consolidation process. The low permeability gas can be used to produce holes or voids in a cladding region of an optical fiber preform. Upon drawing the optical preform into an optical fiber, the voids become elongated in the direction of draw.</p> |
