The TFN Mini Optical Time Domain Reflectometer (OTDR) is a compact, high-performance fiber optic testing instrument designed for FTTH network construction, maintenance, and fault diagnosis. It combines OTDR, OPM, VFL, OLS, and RJ45 cable testing in one lightweight device. With a dynamic range up to 32 dB and a short event dead zone of 1.5 m, it ensures accurate and efficient field testing. Ideal for field engineers, it supports both touch and key operation, multi-language interface, and long battery life, making it a reliable partner for fiber optic network troubleshooting.
Product Features
📌High-Precision Short Dead Zone Testing
With an event dead zone short as 1.5 m and ranging resolution of 0.05 m, this mini OTDR excels in short-distance patch cord and patch panel testing. It accurately locates faults even in dense fiber environments, making it perfect for FTTH link maintenance and fiber jumper testing.
📌All-in-One Design
Integrates OTDR, Optical Power Meter (OPM), Visual Fault Locator (VFL), Optical Laser Source (OLS), and RJ45 cable tester in one handheld device. Eliminate the need for multiple tools and streamline your field testing workflow.
📌Intelligent Diagnosis & Easy Operation
Features auto-test mode, real-time testing, and self-diagnosis of results for reliable data. The intuitive touchscreen and one-key operation make it accessible for both beginners and experienced technicians.
📌Portable & Long-Lasting Battery
Weighing under 1 kg and equipped with a 6300 mAh battery, it supports up to 12 hours of continuous operation. Its compact design allows for easy carrying in toolkits, ideal for on-the-go engineers.
📌Multi-Language & Connectivity Support
Supports English language for stock units. If you need more languages like French, Spanish, Russian, Arabic, Portuguese, Hindi, and Vietnamese, we can make the custom order for you. Offers USB, Mini-USB, Ethernet, and TF card slots for easy data export and remote operation.
