Power Cable Fire Detection & Temperature Monitoring (DTS)
±0.5°C accuracy and 0.8 m spatial resolution, turning a single fiber into thousands of temperature sensors for fire early-warning and temperature monitoring of linear assets.
| Specification | Leading international vendors* | LandSub Global |
|---|---|---|
| Temperature accuracy | ±1 °C | ±0.5 °C |
| Temperature resolution | 0.01–0.1 °C | 0.1 °C |
| Spatial resolution | 0.65–1 m | 0.8 m |
| Range | 35–70 km | 20 km (MM) / 30 km (SM) |
| Response sensitivity | Not disclosed | 50 °C/min |
*Based on publicly available specifications of leading international DTS vendors, as of Aug 2026. Temperature accuracy (absolute) and resolution (relative) are separate metrics.
