16-in-1 Mini Optical Time-Domain Reflectometer (OTDR)

With a 4.3-inch capacitive touchscreen, this versatile OTDR integrates 16 functions, including auto and expert OTDR, event map, optical power meter (OPM), light source (LS), visual fault locator (VFL), RJ45 cable tracker, 10G OPM, optical loss test, ONU state testing, and more. It offers a maximum dynamic range of 28dB and 8GB of internal memory, capable of storing over 200,000 test curves. Powered by a 4000mAh high-density lithium polymer battery, it supports more than 8 hours of continuous operation and can be charged via a power bank for added convenience. The fiber optic testing device measures parameters such as fiber length, loss, and connection quality, making it ideal for FTTx networks, construction projects, maintenance, emergency repairs, and production testing. Its compact design, weighing only 350g, and shock-proof casing ensure reliable performance in field environments.
