Feature:1. LCD DISPLAY: Equipped with a large LCD screen, allowing users to easily grasp the test results in real time. The one touch operation enables users to complete tests with a simple press of a button.2. DATA PROCESSING: Test data can be uploaded to a PC via the USB port, allowing further analysis or processing using management software. It can also be saved as .sor format files or printed in bulk. The report includes testing conditions, test curves, link loss, average loss, and more.3. FTTx AND ACCESS NETWORK EVALUATION: Suitable for assessing the construction and maintenance of FTTx and access networks. The OTDR tester can identify optical breakpoints, measure cable length, and calculate relative optical power loss.4. HIGH ACCURACY MEASUREMENTS: The optical time domain reflectometer provides accurate and reliable measurements, ensuring the accuracy needed for important network testing and troubleshooting.5. EFFICIENT WORKFLOW: With its user friendly interface and simplified operation, the instrument streamlines the testing process, enabling users to quickly and efficiently perform various optical tests without complications.Specification:Item Type: OTDR Line Finder Set Mode: 1650 PONMaterial: ABS Voltage: 100-240VOTDR Function:OTDR Blind Area: Approx. 3 meters / 9.8ft(event) 10m / 32.8ft (attenuation)Test Pulse Width: 10, 30, 100, 300NS or 1, 3, 6USTest Length: Approx. 60000m / 196850.4ft(event) 30000m / 98425.2ft(attenuation)Scattering Depth: 20DB(6US)Measurement Resolution: Approx. 0.6m / 2ftStandard Optical Power Meter:Number Wavelength Range: 800 to 1600NM/SC portTest Range: -70 to +6 (-50 to +26 broadcast version)Red Light Source:Operating Wavelength (nm) : 650nmOutput Power (mw) : 10mwLight Loss Test Function:Test Range: 0 to 30DBOutput Power: 10%LTDR Test:Test Length: Approx. 200m / 656.2ft by defaultTest Function: Measure the breakpoint or short circuit of the network cableHunting Function:Test Method: Sound, ultra sound testTest Range: Between 12 and 36PON Power Meter:Test Interface: ONU OLT test interfaceTest Function: Verify and verify the optical fiber of the broadband catLine Test:Test Function: Network cable ring resistance measurement, Network cable sequenceDisplay Description: 0K is normal, X is faultyOther Functions:OTDR Battery: Lithium battery x 1 (4000mAH) (shipped with built in battery)Line Finder Battery: Lithium battery x 1 (1000mAH) (shipped with built in battery)Temperature: -10 to +50(working), -25 to +70 (storage).Package List:1 x OTDR 1 x Line Finder 1 x Aluminum Alloy Toolbox 1 x Charger 1 x USB Charging Cable 1 Bag x Cotton Swab 2 x Accessory
