Product Overview
The DT-800 Series OTDR is a compact, handheld optical time-domain reflectometer designed for fast and accurate fiber testing. It features a 4.3-inch capacitive touch screen and integrates multiple fiber testing functions into one portable device. Intelligent measurement, simple parameter settings, and long battery life make it ideal for field installation, maintenance, and troubleshooting.
The DT-800 supports fiber length, loss, attenuation, return loss, and event analysis with automatic optical protection to prevent module damage. Filtered models allow online testing up to –2 dBm, making it suitable for live network environments.
