摘要： An induction furnace capable of drawing large diameter preforms of up to 130 mm is described. The induction furnace has top and bottom chimneys surrounding the entire preform during operation of the furnace with an inert conditioning gas which is introduced into the top chimney and flows downward through the furnace body and bottom chimney without significant turbulence. A distributor ring inside the top chimney redirects flow from a circumferential direction to a downward direction. The top chimney also includes a resilient seal to releasably hold the top of the preform. The bottom chimney has a smoothly decreasing cross-sectional area preventing turbulence at the furnace exit. The furnace insulation is preferably a rigid self-supporting graphite cylinder. A method of drawing large diameter preforms either to an optical fiber or to a preform of smaller diameter using such a furnace is also described.

摘要： An optical fibre tensioning device, receiving at its input an optical fibre from a traction device and capable of supplying the optical fibre from its output to a device for storing the fibre. The tensioning device comprises at least one fixed pulley on which the optical fibre is wound for a first length, and at least one movable pulley on which the optical fibre is wound for a second length. A device for measuring the tension applied to the fibre and a motorized device for moving the movable pulley interact with each other to control a distance (Dp) between axes of the pulleys in such a way as to automatically keep the tension applied to the fibre essentially constant.
