Fusion splicer mainly include optical fiber welding machines and high frequency welding machine, ultrasonic welding machine, rotary welding machine, etc. Widely used in all walks of life, gifts, toys, supplies, optical fiber cable line construction, line maintenance, emergency repair, production test of fiber optic devices and scientific research institutes of research teaching. Mainly by the discharge of the arc will be two optical fiber fusion, at the same time by using the principle of the collimating gently forward, in order to realize the coupling of optical fiber mode field. Note: the optical fiber is every fiber in the fiber optic cable.
