VFLTOOL Visual Fault Locator 30KM Fiber Light Pen Kit for Fiber Network Cable Test VFL Fiber Optic Cable Tester Detector Meter with Universal 25mm Adapter for FC SC ST LC Connectors Aluminum

【Accurate Fiber Identification】This visual fault locator accurately detects and locates fiber optic breaks, poor connections, bending, or cracking. It can operate in both CW and Pulsed mode, emitting a light for fiber tracing and locating. Breaks or faults will refract the light in the fiber, making it easy to identify the issue., 【Multiple Functions】The fiber tester has multiple functions, including constant output power, low battery warning, long battery life, and long-distance detection. It efficiently checks fiber routing and continuity, creating a bright glow around the faulty area for easy identification., 【Wide Compatibility】The universal 2.5mm connector is designed to interfere with LC, ST, SC, and FC in both the circle and square shapes of different fiber optic cables. It can test both single-mode and multi-mode cables, making it ideal for integrated wiring systems and Fiber Optic engineering, CATV Engineering optic network Maintenance, Optical Telecommunications, Optical Measurement drive engineering, Optical device production, and research., 【Long Detection Distance】This visual fault locator has a powerful light source output of 50KM with a constant output power. The fiber light can travel up to 30 kilometers in a fiber optic cable. The high effective power circuits provide stable power and can operate in both continuous-wave and pulsed mode., 【Practical and Portable Design】This visual fault locator is small, lightweight, and has a pen-type design with a pouch, making it easy to carry around. It features a stainless steel head and aluminum body to prevent crash and dust. The case ground design efficiently prevents ESD damage.
