| Abstract: | tIn this paper the processing of MCVD preform was theoreticallyanalysed in detail, and a thermophoresis model was developed that explainswhy soot collects on the tube wall. The foundational principle of that modelis in agreement on what has happened in the experiment. The structureanalysis of graded-index optical fibre shows that the profile parameter aand numerical aperture (NA) can be acourately controlled by means ofMCVD which provides the application to increasing deposition rate andproduction efficiency. |
