Abstract
A continuous optical fiber manufacturing process utilizes the method of chemical vapor deposition of the glass forming materials within an R.F. excited glow discharge. The rapid deposition rate within the discharge provides a sufficient stream of glass material for winding into a finished fiber on a synchronous take-up mechanism. Alternate embodiments include an oxygen air stream to remove dust particles from the fiber surface and an in-line fluorine stream to terminate surface bonding and reduce moisture attack on fiber surfaces.
