Description: Using the core of the light cable in the red light pen, it is possible to detect whether the fiber is connected, fault location such as fiber breakage and bending, fault detection in the OTDR blind zone, and optimization of the mechanical connection point. The fiber power is 1mw=5km, and the working duration can reach more than 50 hours. Used in telecommunications, CATV engineering and maintenance, optical communications, optical measurement, optical drive engineering construction, fiber network maintenance, optical device production and research, integrated wiring systems, and other fiber engineering. Ergonomic design, comfortable and beautiful, low battery alarm circuit design, remind customers to replace the battery before the battery energy is exhausted. There are two working modes: steady on and slow flash (2HZ). Specification: Name: 1mW/5km red light pen Output wavelength: 650nm Modulation method: CW/2Hz Fiber Type: SM MM Fiber Optic Adapter: Universal Connector Battery type: 7 alkaline battery 2 knots (not included) Package Includes: 1Pcs Visual Fault Locator Note: Battery is not included
