Fiber Visual Fault Locator 30mW, VFL Fiber Optic Cable Tester Meter, Red Light Pen Tester Adapt LC/FC/SC/ST Interface, Fiber Network Cable Test Kit 30km Fiber Light Source Testers

【Accurate Identification】This product can easily and accurately detect and locate fiber optic breaks, poor connections, bending or cracking. It can operate either in CW or Pulsed mode. VFL will emit a 650nm red light for fiber tracing and locating, breaks or faults will refract the light in the fiber. 【Excellent Functions】The fiber tester multiple functions include constant output power, lower battery warning, long battery life, and long-distance detection. Fiber routing and continuity checking efficiently, creating a bright glow around the faulty area. 【Wide Application】Universal 2.5mm connector designed for LC, ST, SC, FC interferes both in the circle and square shape of different fiber optic cables, test for both single-mode and multi-mode cables. Apply To: Integrated wiring systems and Fiber Optic engineering; CATV Engineering optic network Maintenance; Optical Telecommunications; Optical Measurement drive engineering; Optical device production and research. 【Detection Distance】This visual fault locator has a strong light source output power of 30mW, constant output power the strong red light goes 20-30 kilometers far in fiber optic cable, high effective power circuits provide stable power, continuous-wave and pulsed mode. 【Practical Design】Battery included, no additional purchase required. Small size and lightweight, pen-type design with pouch make it portable, easy to check fiber faults with visual fault locator, design with a stainless steel head and aluminum body to prevent crash and dust, the case ground design prevents ESD damage efficiently.
