摘要： A method of producing an optical fiber is provided that includes the steps of flowing a first gas into an optical fiber draw furnace (10). The first gas G1 is passed through a heated section (18) configured to contain and heat a glass source or optical fiber preform (30) from which the optical fiber (34) is drawn, passing the first gas G1 through a muffle (22) which defines a capture chamber (46). A portion of the first gas G1 is removed through at least one reclaim port (50) operatively coupled to the capture chamber (46). A second gas G2 flows into a gas screen (26) at a rate configured to substantially recover a pressure drop associated with removing the portion of the first gas G1.

摘要： Control of speed and uniformity of the heating of the working zone of the preform in a glass drawing operation in which the softening heat is applied by forced convection (13), using a separate fluid heating zone to introduce temperature and velocity controlled fluid. The size of the working zone is further controlled by changing (18) the configuration of a movable exit sleeve. Uniformity and accuracy of temperature is enhanced by normalization (10) of the temperature of the preform close to a preselected value before the preform enters the furnace. A glass drawing apparatus embodies the preferred means to carry out the process, providing a two-chamber furnace having an air heating chamber (44) connected by air delivery channels (51) to a drawing chamber (43). The drawing chamber has preform inlet (41) and a drawn product outlet (56). Each of the latter preferably has an adjustable opening diameter. The inlet is provided with a pre-cooling collar (35). The outlet has an insulated, movable sleeve (62) controlling the effective distance from the inlet to the outlet by modifying the temperature gradient. The latter provides means for controlling the length and shape of the working zone (55).
