Method For Fabrication Of Optical Fibre Soot Preform
Abstract: The present disclosure provides a method for fabrication of an optical fibre soot preform (122). The method includes production of silicon dioxide particles (108) along with waste particulates. The silicon dioxide particles (108) are produced using a precursor material in a combustion chamber 10 (102). In addition, the method includes cooling of the silicon dioxide particles (108). Further, the method includes agglomeration of the silicon dioxide particles (108). Furthermore, the method includes separation of the waste particulates from the silicon dioxide particles (108). Moreover, the method includes dehydration of the silicon dioxide particles (108). Also, 15 the method includes compaction of the silicon dioxide particles (108). The compaction of the silicon dioxide particles (108) facilitates fabrication of the optical fibre soot preform (122)
