Abstract
A furnace minimizes the lowering of the quality of optical fibers, especially those lowerings of the quality that stems from variations of the conditions inside of the furnace. These variations can occur when a preform is connected to an auxiliary quartz rod of differing diameters. Also, the furnace has an inlet sleeve which minimizes fluctuations in flow speed of the inert gases and the pressures inside the furnace.
