Problems solved by technology

[0004] In the process of manufacturing fluorinated clad plastic optical fiber, the coating device is often used. The existing coating device lacks a complete winding mechanism, resulting in that the optical fiber preform cannot be well preserved after coating, reducing the coating cost. Quality; the existing coating device cannot realize the function of automatic lifting, which causes the liquid level to drop when the coating is consumed, and the coating roller cannot touch the coating, which affects the coating efficiency

Description

technical field [0001] The invention relates to the technical field of optical fiber production, in particular to a method for manufacturing a fluorinated clad plastic optical fiber. Background technique [0002] Plastic optical fiber is a type of optical fiber made of highly transparent polymers such as polystyrene, polymethyl methacrylate, and polycarbonate as the core material, and PMMA, fluoroplastic, etc. as the skin material. Different materials have different light attenuation properties and temperature application ranges. Plastic optical fiber can not only be used in the last 100-1000 meters of the access network, but also can be used in various vehicles, aircraft, and other vehicles, and is an excellent short-distance data transmission medium. [0003] The fluorination process or surface fluorination treatment technology has been rapidly developed and applied in developed countries in the world. So far, the most notable commercial applications of surface fluorinat...
