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.Specification:Item Type: OTDR TesterCentral Wavelength: 1310nmApplicable Fiber Type: Single ModeMinimum Event Blind Area: Approx. 10m / 32.8ft (Single Mode)Dynamic Range: 24dBMeasuring Range: 0.2km, 0.5km, 1km, 2km, 4km, 8km, 16km, 32km, 64kmMeasuring Pulse Width: 3ns, 5ns, 10ns, 30ns, 50ns, 80ns, 160ns, 320ns, 500ns, 1us, 5us, 10usSampling Points: 64000Waveform Data Storage Capacity: 500 PiecesRefractive Index Setting Range: 1.00000-1.99999Optical Cable Correction Coefficient Range: 0.80000-1.0000RJ45 Cable Sequence: Network cable sequence test, use with the line aligning deviceOptical Power Meter Measuring Range: -50dBm to +26dBmVFL Output Power: >10mWRJ11 Cable Tracer: The RJ11 interface emits an electrical signal for use with the detectorLCD Display: 320x480, 3.5 Inch Color LCDInterface: Micro USB, Micro Memory CardPower Supply: AC DC Adapter:Input Voltage: 100V-240V (1.5A)Frequency Allowed Range: 50/60HzOutput: DC 5V 1AInterface Language: Simplified Chinese, EnglishStorage Temperature: -40-70Relative Humidity: 5%-95%, no condensationProduct Size: Approx. 173 x 82 x 36mm / 6.8 x 3.2 x 1.4inExternal Storage Type: Micro Memory Card (not included)Tester Battery: 1 x 3.7V 4000mAh Lithium Battery (built in)Battery Working Time: 10 Hours (room temperature)Cable Tracer Battery: 1 x 9V 6F22 Battery (not included).Package List:1 x OTDR Tester2 x Connecting Cables1 x Crocodile Clip Cable1 x Earphone1 x USB Cable1 x Plug6 x Accessories1 x Wire Stripper1 x Cable Tracer1 x Storage Bag1 x Portable Strap1 x User Manual
