PROCEDE POUR LA FABRICATION D'UNE TIGE EN VERRE REVETUE D'UNE COUCHE D'UN AUTRE VERRE |
摘要 |
A method of producing clad glass rod of uniform diameter from which an optical fibre is drawn. The rate of drawing of the rod from a glass melt and the diameter of the drawn rod are sensed and the sensed values are fed to a coarse open loop control and a high gain closed loop control which regulate the draw speed of the rod and the movement of a cooling jacket which cools the rod as it is drawn. |
