FVS-04 Flash vaporization doping system is an add-on device for preform fabrication equipment, for CVD and OVD processes. System generates special silica or glass dopant precursor vapors by evaporation from solutions. This permits vapor phase (in-situ) deposition of silica in fabrication of rare earth- or metal ion-doped preforms for active and special optical fibers.
