Feature: 1. Accurate Recognition: This visual fault locator can easily and accurately detect and locate fiber optic breaks, poor connections, bends or ruptures. It can operate in continuous wave or pulse mode. VFL emits 650nm red light for fiber tracking and positioning, and breaks or malfunctions can refract light in the fiber. 2. Excellent Performance: The fiber optic tester has multiple functions such as constant output power, low battery warning, long battery life, and remote detection. Effectively conduct fiber optic wiring and continuity checks to generate bright light around the faulty area. 3. Wide Application: A universal 2.5mm connector designed specifically for LC, ST, SC, and FC, which can interfere in circular and square shapes of different optical cables and can be used for testing single mode and multimode cables. Suitable for comprehensive wiring systems and fiber optic engineering, CATV engineering optical network maintenance, optical communication, optical measurement drive engineering, production and research of optical devices. 4. Detection Distance: The visual fault locator has a strong light source output power of 10mW, and a constant output power. The strong red light propagates 10km maximum in the optical cable. The high effective power circuit provides stable power, continuous wave, and pulse modes. 5. Practical Design: Small in size and light in weight, the pen style design with a bag makes it easy to carry, and optical fiber faults can be easily detected through a visual fault locator. The stainless steel head and aluminum body design can prevent collisions and dust, and the shell grounding design can prevent effective ESD damage.
