APPARATUS AND METHOD FOR MAKING AN OPTICAL FIBER PREFORM |
摘要 |
An apparatus is provided for applying a tensile force along the longitudinal axis of a cane assembly during the deposition of soot thereon to produce an optical fiber preform. Fiber drawn from such a preform exhibits improved core/clad concentricity. The tensile force may be applied at one or both ends of the cane assembly, with application at both ends being preferred. The tensile force may he varied during the deposition of soot. The cane assembly may be annealed prior to beginning the deposition of soot thereon.
