Distributed temperature sensing (DTS) systems are optoelectronic devices that are used to measure temperatures using an optical fiber cable that functions as a linear sensor. The optical cable acts as a multi-point temperature sensor and provides cost-effective temperature measurement along its entire length. It provides critical temperature data pertaining to various applications and is considered as the best option for monitoring multiple temperature sensing points in difficult operating conditions. DTS systems enable accurate detection of temperatures over long distances. Industries such as oil & gas and pipeline transportation require temperature sensing systems for monitoring purposes that can operate at high temperatures and harsh working environments, and are immune to electromagnetic interferences.
The overall distributed temperature sensing market is expected to grow from USD 734 million in 2020 to USD 958 million by 2025, at a CAGR of 5.5%. The growth of this market is mainly driven by increasing demand for labor safety at working sites, reliability of DTS systems/sensors for sensing and monitoring applications in harsh environments, and increasing applications in the oil & gas industry. Increasing safety norms and supportive government policies related to leakage detection and increasing adoption of data-based analytics provide major opportunities for the growth of the distributed temperature sensing market.
The market for optical time domain reflectometry (OTDR) operating principle based DTS systems expected to grow with the highest rate during forecast period. OTDR is the most widely used technology and has been in use since the inception of DTS systems. It helps in providing a robust measurement and is less susceptible to issues such as reflections and bends in the fibre and accessories. The technology utilizes the time of flight principle to measure the backscattered light during the Rayleigh scattering and Fresnel reflecting in the optical transmission generated by a narrow laser pulse.

The multimode fibers is expected to hold the largest share of the distributed temperature sensing market during the forecast period. The Multimode fiber has a relatively large light carrying core. These are available in core sizes of 50µm and 62.5µm and are widely used in DTS applications. The transmitted rays of light are allowed to follow multiple paths within the fiber. The large core diameter helps to propagate more optical power in the fiber. The signal undergoes dispersion since many modes are present and hence there is more power loss as compared to single mode fiber, which eventually restricts the signal carrying capacity in terms of distance covered.
The market for oil & gas application is expected to hold the largest market size during the forecast period. The DTS technology has become an integral part of the oil & gas industry. DTS systems help in continuous, real-time downhole monitoring to optimize the operational and economic performance of the assets. This enables the reservoir engineer to gain a better understanding of the injection and production dynamics and accordingly optimize the production and improve recovery leading to improved profit. Hence, there is an increasing focus on adopting the technology for improving the productivity of brownfield operations. The analysis of the data collected by the DTS system can provide additional information on the well behavior such as the flow volume within a particular section of the well.
The distributed temperature sensing market in APAC is expected to grow at the highest CAGR during the forecast period. The increasing construction activities worldwide and the expanding power transmission cables in technologically advancing countries in APAC such as China and India are contributing to the growth of the DTS market in this region. India, China, South Korea, and Australia are some of the major countries contributing to the growth and development of the DTS market in this region. In addition, the presence of several oil & gas industries in this region is driving the growth of the DTS market in APAC.
