ABSTRACT:
The separate steps of forming an optical fiber preform and then drawing the fiber are combined into an essentially simultaneous process wherein a "stub" preform (18) is formed by means of the so-called "vapor-phase axial-deposition" method while the fiber (17) is simultaneously drawn from the end of the stub that is opposite to the end upon which the particulate matter (14, 15) is being deposited.
