Fiber visual fault locator is 650nm (±20nm) semiconductor laser as a light emitting device, driven by a constant current source to emit stable red light, and optical interface into the fiber, so as to achieve fiber fault detection function. It is mainly used in telecom /CATV engineering and maintenance, cabling construction and maintenance, optical device production and research and other optical fiber engineering.It is also called pass-light pen, pen-type red light source, visible light detection pen, optical fiber fault detector, etc. Most of them are used to detect optical fiber breakpoints.
On the premise of satisfying the comprehensive network wiring, optical fibers often appear bare fiber, disk fiber, fiber fusion, etc. Therefore, fiber visual fault locator has become one of the common optical fiber detection tools for troubleshooting network faults.Features of fiber visual fault locator are as follow:
