| titleOfInvention | Manufacturing method of optical preform |
| abstract | A method for improving the efficiency of a deposition process is provided. The present invention relates to a method of manufacturing an optical preform by performing one or more chemical vapor deposition reactions in a substrate tube, the method comprising: (I) supplying the substrate tube with one or more doped or undoped glass forming precursors; (Ii) performing a reaction between the reactants supplied into the substrate tube in step (i) to form one or more glass layers inside the substrate tube, wherein step (ii) It includes only the formation of an internal pulsed plasma zone.
