Feature: 1. Multiple Functions: Intelligent fiber optic comm measurement instrument, with fiber optic comm measurement, network cable sequence, optical power meter, stable light source, VFL, RJ11 line finding, and other diverse functions. 2. Optical Power Meter: The measurement range of optical power meter is ?50dBm to +26dBm, suitable for signal power testing, insertion loss testing, etc. of various devices and optoelectronic components, efficient and practical. 3. Visual Fault Locator: Accurately determine the location of fiber fault points, detect bare fiber optic cables, fiber optic jumpers, and other fibers that can leak red light, near end fault points, and high loss sections caused by micro bending. 4. Color LCD Display: The OTDR fiber optic tester adopts a 3.5 inch color LCD display, which clearly displays the loss distribution curve, fiber distance, loss, and attenuation of the fiber and optical cable, making it clear and intuitive. 5. Power Supply: The OTDR tester has a built in 3.7V 4000mAh lithium battery (included), with a working time of 10 hours. The cable tracer is powered by a 9V 6F22 battery (not included), which is convenient for use at any time.
