Item Type: Visual Fault Locator_x000D_ Model: B2-10_x000D_ Fiber Optic Adapter: Universal Connector_x000D_ Output Distance: 10km_x000D_ Output Wavelength: 650nm 10nm_x000D_ Output Fiber Power: 10mW_x000D_ Operating Temperature: 0~+60 _x000D_ Storage Temperature: -20-+70 _x000D_ Battery: 2 x AA battery, shipped without battery. 1Accurate 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. 2Excellent 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. 3Wide 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. 4Detection 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. 5Practical 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. 1 x Visual Fault Locator 1 x User Manual 1 x Ceramic Core 1 x Bag 1 x Lanyard
