Feature 1ACCURATE IDENTIFICATION: This visual fault locator easily and accurately detect and locate broken, poorly connected, bent or broken fibers. Can operate in continuous wave or pulse mode. The VFL emit a 650nm red light for fiber tracking and positioning, and breaks or faults refract light in the fiber 2EXCELLENT FUNCTION: The optical fiber tester has a variety of functions such as constant output power, low battery warning, long battery life, remote detection and so on. Efficiently perform fiber cabling and continuity checks to produce a bright glow around the fault area 3A WIDE RANGE OF APPLICATIONS: Universal 2.5mm connectors are designed for LC, ST, SC, FC, can interfere in the circle and square of different optical cables, can be used for single mode and multi mode cable testing. Suitable for integrated wiring system and optical fiber engineering; CATV engineering optical network maintenance; Optical communication; Optical measurement drive engineering; Optical device production and research 4DETECTION DISTANCE: This visual fault locator has a 30mW strong light source output power, a constant output power strong red light propagate 30km(maximum) in the cable, a high effective power circuit provide stable power, continuous wave and pulse modes 5PRACTICAL DESIGN: Small, lightweight, pocketed pen design make the visual fault positioner easy to carry and easily check for fiber optic faults, stainless steel head and aluminum body design prevent collisions and dust, and housing grounding design prevent ESD damage effectivelyItem Type: Visual Fault LocatorFiber Optic Adapter: Universal connectorOutput Distance: 30kmOutput Wavelength: 650nm 10nmOutput Fiber Power: >30mWOperating Temperature: 0~+60Storage Temperature: -20~+70Battery Type: 2 x AA battery(not include) .wang-edit-text{ font-family:'Arial' !important; } .wang-edit-text table { border-top: 1px solid #000; border-left: 1px solid #000; } .wang-edit-text table td, .wang-edit-text table th { border-bottom: 1px solid #000; border-right: 1px solid #000; padding: 3px 5px; } .wang-edit-text table th { text-align: center; }Package List1 x Red Light Pen1 x User Manual1 x Ceramic Core1 x Red Light Pen Case1 x Lanyard
