Specification:

• 25 cm spatial sampling
• 5 s temporal sampling
• Up to 10 km measurement length
• 4 channels
• Suitable for remote and hostile environmental conditions

Application:

• The DTS method uses temperature-dependent Raman scattering in fiber optic cables to determine temperature along the cable path
• The measured cable temperature is a proxy for an environmental temperature, depending on how it is installed (for instance, air, soil or water temperature)
• Fiber optic cables are deployed in water bodies (headwaters, lakes, rivers) to spatially identify groundwater-surface water interactions
