Basic working principle of optical fiber fusion splicer

1. Alignment: The current fiber fusion splicer is to align the cores of two optical fibers, and find the core of the optical fiber through the CCD lens.

2. Discharge: The two electrode rods release an instantaneous high voltage (several thousand volts, but a very short moment) to achieve the effect of breaking through the air. After breaking through the air, an instant arc will be generated. The arc will generate high temperature, which will already be The front ends of the two quasi-fibers are melted. Since the fiber is made of silica, that is, glass (of course, the purity of the fiber is much higher), it is easy to reach the molten state, and then the two fibers advance slightly, so The two fibers are glued together.
