Combined with ergonomic design, it is mini and compact, simple to operate, easy to carry, and equipped with light-emitting diodes for status indication. It can be used for visual testing of optical fibers, optical cables, and connectors. When the tested optical fiber has a breakpoint, the laser light transmitting along the optical fiber will leak red light at the breakpoint, and the visible light can determine the position of the breakpoint. The effect depends on the fiber protective layer and the color of the cover.
