DTS Optical Fiber - Premium Industrial Supplier |
Optical fiber for Distributed Temperature Sensing (DTS) serves as the backbone of modern continuous temperature monitoring systems deployed across oil & gas pipelines, power cables, tunnels, and industrial process environments. Unlike conventional point sensors, DTS optical fiber transforms the entire cable length into a dense array of temperature measurement points, delivering spatial resolution as fine as 0.25 m over distances exceeding 30 km in a single fiber run. Our premium-grade DTS fiber cables are engineered to withstand harsh mechanical, thermal, and chemical conditions while maintaining measurement accuracy within ±0.1 °C. Manufactured under strict ISO 9001 quality management protocols and compliant with IEC 60793 and ITU-T G.652 standards, these fibers find extensive application in subsea installations, geothermal wells, smart grid infrastructure, and fire detection systems. Whether you require a tight-buffered indoor design or a double-armored subsea variant, our mill-direct supply chain ensures cost-effective sourcing with rapid global delivery.
What is Optical Fiber for Distributed Temperature Sensing (DTS)?
DTS optical fiber is a specially engineered single-mode or multimode glass fiber that exploits the Raman backscattering effect to measure temperature continuously along its entire length. When a laser pulse travels through the fiber, thermally sensitive Stokes and anti-Stokes signals are reflected back, allowing a DTS interrogator unit to calculate precise temperature profiles at every point without requiring any active electronics in the field.

Optical Fiber for Distributed Temperature Sensing (DTS) Manufacturing Process
Production begins with ultra-pure silica preforms fabricated via Modified Chemical Vapor Deposition (MCVD) or Outside Vapor Deposition (OVD), achieving hydroxyl (OH⁻) ion content below 1 ppb to minimize attenuation. The preform is drawn into fiber at temperatures exceeding 2,000 °C, then coated with dual-layer acrylate or polyimide at diameters of 250 µm. Subsequent cabling stages apply gel-filled loose tubes, steel or aramid strength members, and HDPE or LSZH outer jackets rated from −40 °C to +300 °C depending on the application profile.
Optical Fiber for Distributed Temperature Sensing (DTS) Technical Specifications
Core/cladding geometry conforms to 50/125 µm (multimode OM3/OM4) or 9/125 µm (single-mode G.652.D). Attenuation is ≤0.20 dB/km at 1,550 nm and ≤0.35 dB/km at 1,310 nm. Numerical aperture reaches 0.200 ± 0.015 for multimode variants. Operating temperature range spans −40 °C to +300 °C (polyimide-coated), with a tensile load rating of 2,700 N minimum per IEC 60794-1-2 Method E1. Bend radius is maintained at ≥10 mm under installation and ≥5 mm long-term, ensuring signal integrity throughout the cable lifecycle.
