Pocket-sized tool projects a visible red laser light along the fiber to find any breaks or unseen faults

This pocket-sized tool is a real lifesaver to the installer or technician. It sends a visible red laser light through fiberoptic cables. Breaks or faults in the fiber will refract the light, and create an easy-to-see bright glow around the faulty area. The universal connector (2.5mm ferrule) can be used for all common fiber interfaces.
