Mini Fiber Optic OTDR Tester with VFL and OPM

This compact fibre optic tester combines OTDR testing with optical power meter, light source and visual fault locator functions in one portable unit. With a touchscreen interface, up to 70km practical testing range and dual-wavelength testing, it helps technicians locate faults and assess fibre links efficiently.

Key Features

• 6-in-1 Fibre Testing: Combines OTDR, optical power meter, optical light source, visual fault locator and LED lighting functions in one compact device.
• High-Precision OTDR: Supports automatic, average and real-time testing modes for flexible fibre diagnostics.
• Up to 70km Testing Range: Suitable for testing long single-mode fibre links and locating faults across extended cable runs.
• Dual-Wavelength Testing: Supports 1310nm and 1550nm testing for detailed fibre analysis and macro-bend detection.
• 0.5m Resolution: Helps pinpoint faults, bends, breaks and connection issues with fine distance resolution.
• 24,000 Sampling Points: Captures detailed fibre trace information for more accurate analysis.
• Event Map: Converts test results into an easy-to-read event map to simplify fault identification.
• 3.5-Inch Multi-Touch Display: Capacitive touchscreen allows intuitive operation, zooming and trace inspection.
• Built-In OPM: Optical power meter supports a broad measurement range from -50 to +26dBm.
• Visual Fault Locator: 650nm laser helps identify visible breaks, bends and connection faults.
• Easy Data Export: Save test results and screenshots, then transfer files via USB for documentation and printing.
• Portable Design: Lightweight 300g construction makes it convenient for field technicians and network installers.
• Long Battery Life: Rechargeable lithium battery provides more than 6 hours of continuous operation.
• USB-C Connectivity: Convenient Type-C charging and data connectivity.
