Inside the sensing fiber, the laser pulse generates Raman backscattering. The Stokes signal is relatively stable and used as a reference, while the Anti-Stokes signal increases as temperature rises. HZ-DTS calculates temperature from the Anti-Stokes / Stokes ratio and uses OTDR return time to locate the event along the fiber.
When the local fiber temperature rises, molecular vibration increases. This strengthens the Anti-Stokes Raman backscatter, while the Stokes signal remains comparatively stable. The ratio between the two signals is converted into temperature.
The DTS analyzer sends short optical pulses into the sensing fiber.
Stokes and Anti-Stokes Raman signals return from each point of the fiber.
A stronger Anti-Stokes signal indicates higher local fiber temperature.
Return time maps the temperature result to an accurate distance location.
HZ-DTS is designed for continuous fiber optic temperature monitoring along power cables, data centers, pipelines, tunnels and critical infrastructure routes where operators need early hotspot detection and accurate event localization.
Monitor underground cables, cable tunnels, joints and cable routes to detect overheating, insulation risks and abnormal thermal events.
Data CenterTrack temperature changes along power cable routes, busduct areas, battery rooms and critical power infrastructure in data centers.
PipelineDetect thermal anomalies along pipeline routes and support leak-related temperature monitoring for oil, gas and industrial pipelines.
SubstationMonitor cable exits, cable trays, transformer cable routes and power distribution areas for abnormal temperature rise.
TunnelUse passive sensing fiber for early fire detection and hotspot localization in tunnels, utility corridors and underground spaces.
Product FamilyCompare HZ-DTS with distributed acoustic sensing and intelligent fiber optic monitoring systems for long-distance asset protection.
Essential parameters for distributed fiber optic temperature sensing, power cable monitoring, data center thermal monitoring, pipeline temperature monitoring and long-distance hotspot localization.
Note: Monitoring distance, channel number, sensing fiber type, relay output and alarm strategy should be configured according to the asset route and project requirements. For single-mode long-distance projects, HZ-DTS-1004S can support up to 20 km monitoring distance.
