Gato E3 DTS Fiber employs Raman scattering and OTDR to turn the fiber itself into a sensor. The system delivers ultra-fast data collection at 1-second intervals per channel with unmatched precision of ±0.5 meters in location accuracy and ±0.5°C in temperature measurement. Capable of single-channel monitoring over 16 kilometers, it employs three-tiered alarm strategies (fixed threshold, differential temperature, and rate-of-rise detection) for comprehensive protection. Auto-calibration, browser-based management, and fast deployment make it plug-and-play for tunnels, energy storage, and pipe galleries.
