Abstract

PURPOSE:Glass soot prepared by heating the starting material of liquid glass composition with micro waves is heated, molten, and taken off to form multicomponents and low light-loss fibers very inexpensively. CONSTITUTION:Crucible 2 is filled with liquid starting materials 3, placed in micro- wave heater 1 that is kept under oxidative atmosphere and heated until the liquid starting materials is dehydrated and defoamed to form glass soot 6. Then, stopper 5 on nozzle 4 of the crucible is removed and the soot 6 is changed to molten glass 6', which is spun from nozzle 4 into glass fiber 8, passed through polymer applicator 9, and wound up on drum 11, thus giving optical fiber with polymer clad 10.
