Feature:1. OTDR Tester: Multifunctional optical time domain reflectometer with cable tracer, supporting with light testing, with a center wavelength of 1550nm, suitable for single mode fiber types, and has a wide measurement range.2. Multipurpose Design: With diversified functions such as fiber optic comm measurement, network cable sequence test, optical power meter, stable light source, VFL, RJ11 line finding, etc., which can meet various needs.3. Optical Power Meter: The measurement range of optical power meter is 50dBm to+26dBm, used for signal power testing, insertion loss testing, and other testing of various equipment and optoelectronic components.4. Visual Fault Locator: Accurately determine the location of fiber optic fault points, detect bare fibers, fiber optic jumpers, and other fibers that can leak red light, near end fault points, and high loss sections caused by micro bending.5. LCD Display: The OTDR tester uses a 3.5 inch color LCD with a clear testing interface, displaying parameters such as loss distribution curves, fiber distance, loss, and attenuation of optical fibers and cables.Specification:Item Type: OTDR TesterCentral Wavelength: 1550nmApplicable Fiber Type: Single ModeMinimum Event Blind Area: 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, 10usSample Number: 64000Waveform Data Storage Capacity: 500Refractive Index Setting Range: 1.00000-1.99999Optical Cable Correction Coefficient Range: 0.80000-1.0000RJ45 Cable Sequence: Network cable sequence test, use with the cable alignment machineOptical 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 Range: 100V-240V (1.5A), frequency allowedRange: 50/60HzOutput: DC 5V 1AInterface Language: Simplified Chinese, EnglishEnvironment Adaptability: Storage 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
