| titleOfInvention | Fiber Optic Substrate Overcladding Manufacturing Equipment |
| abstract | end. The technical field to which the invention described in the claims belongs.n n n The present invention relates to an optical fiber base material over cladding manufacturing apparatus.n n n I. The technical problem to be solved by the invention.n n n The present invention seeks to improve the productivity of the optical fiber base material production, to prevent the temperature imbalance (temperature gradient) by delivering a sufficient amount of heat, and to enable stable collapsing by the pressure of acid and hydrogen, thereby maintaining the concentricity of the base material cross section. By using acid and hydrogen flow rate with low flow rate, it is possible to manufacture high-strength optical fiber by protecting base surface from impurity particles, and can increase the collapsing speed of large diameter quartz tube by up to 5 times because of the large amount of heat supply. It is to provide an optical fiber base material over cladding manufacturing apparatus capable of over cladding regardless.n n n All. Summary of the Solution of the Invention.n n n The present invention is characterized in that a furnace for preheating or heating the quartz tube to coat the quartz tube on the optical fiber base material during the over cladding of the optical fiber base material is installed in the carriage.n n n la. Important uses of the inventionn n n Applied to the over cladding manufacturing equipment in the optical fiber base material manufacturing process. |
