The working principle of optical fiber welding machine? Q: the working principle of optical fiber welding machine? Answer: the working principle is to use high voltage arc will melt two fiber cross section also let two optical fibers with high precision motion gently push merge into one, in order to realize the optical fiber mode field coupling. Specific as follows: 1, the alignment: now the most commonly used optical fiber welding machine are of two optical fiber core alignment, find the core of the fiber through optical camera ( The quality of the more accurate the better, of course, loss is smaller; Usually imported high precision optical fiber welding machine in domestic optical fiber welding machine) 。 2, discharge: two rods electrode release of instantaneous high pressure ( Probably a few kv) , produce moments of arc, arc will produce high temperature, will have been at the forefront of two optical fiber high temperature melting, and because the fiber is silica material, which is usually said glass ( Optical fiber of higher purity, of course) Melt, will reach the melting point, then two fiber slightly forward, two optical fiber is connected together. 3, hot shrinkage: set of heat shrinkable tube ( Rubber) , the welding parts wrapped in the heating furnace in the optical fiber welding machine for heating, cooling after will protect coated welding parts.
