Abstract
PURPOSE:To produce an optical fiber preform by coating a core rod with a plastic film and by putting the coated rod into a glass tube to protect the rod from scratching when put into the tube and to prevent formation of air bubbles and disproportionation at the boundary in unifying the rod and tube by fusion. CONSTITUTION:In production of an optical fiber preform by a rod-in-tube method, core rod 2 is coated with flexible urea resin film 3 of 5 mu thickness and put into glass tube 1. Cock 6 is closed, ixygen gas is fed from introduction pipe 7 at a rate of 1000 cc/min for 5 min, and oxyhydrogen burner 4 is lowered at a speed of about 60mm/min. Thus, the temp. of tube 1 is raised to about 200-500 deg.C, and film 3 is removed thorougly. Cock 6 is then opened, the caloric force of burner 4 is strengthened, and burner 4 is elevated to unify tube 1 and rod 2 by fusion, giving an optical fiber preform.
