Abstract: An improved process for fabricating a refractory dielectric article, in particular silica optical fiber, is provided. The fabrication process involves joining of two elongated bodies- typically silica preforms - end-to-end by use of an isothermal plasma torch technique and moving at least one of the bodies towards the other until their respective end faces are joined. When the process is applied to an optical fiber preform draw tower, continuous drawing is possible. A long preform made in this manner allows drawing of optical fiber with less down-time and waste than current processes. The plasma torch technique also produces low perturbations within the resultant preform, thereby increasing the amount of usable fiber.
