Fabrication of Optical Fiber Preforms for Optical Communication by Centrifuge - Effects of Fine Particle Sizes and Traversing Injection Tube -

원심력을 이용한 광통신용 광섬유 모재제조 - 미세입자 크기 및 이동식 injection tube의 영향 -

In this paper, the technique to fabricate the optical fiber preforms by centrifuge was investigated, using silica particles of different sizes. The injection tube was designed to traverse axially so that uniform coaling of tiny silica particles onto the substrate tube can be certified. The deposition efficiencies and deposition rates of $SiO_2$ particles were measured to elucidate the effects of process variables such as rotation speed of rotor, aqueous flow rate, suspension concentration, binder concentration and overflow weir diameter. This study shows dearly the merit of this technique by enhancing abruptly the deposition rates and deposition efficiencies, comparing to the conventional processes for optical fiber preforms.
