development of metrological support, improvement of the reference-measuring, scientific-methodical and regulatory-technical base and ensuring the uniformity of measurements of the parameters of laser and optoelectronic equipment. Abstract—Distributed temperature sensors (DTS) measure tem-peratures by means of optical fibers. Those optoelectronic devices provide a continuous profile of the temperature distribution along the cable. Initiated in the 1980s, DTS systems have undergone sig-nificant improvements in the technology.

Distributed Temperature Sensing (DTS) systems provide temperature information for accurate thermal monitoring, fire detection, and condition assessment by utilizing standard fiber optic cables. Advances in optoelectronics and associated signal processing have enabled the development of optical fibre distributed sensors with maximum ranges of several tens of kilometres. The unique feature of a distributed temperature sensing system is that it provides a continuous (or distributed) temperature. Distributed Temperature Sensing (DTS) is a fiber optic technology that enables real-time, continuous temperature monitoring over long distances, used widely in applications like pipeline leak detection, power cable monitoring, and transformer temperature management.

(MEFC) is a Saudi-Japanese (Fujikura) partnership located in Riyadh, Saudi Arabia. MEFC has established itself as the leader in manufacturing fiber optic cables, and solution provider for the telecommunications and industrial sectors in MENA. Fiber optic temperature sensors are deployed across 380 kV and 132 kV substations to monitor transformer windings, cable joints, and GIS equipment in real time, preventing catastrophic failures in the extreme heat of the Arabian Peninsula. Their production capacity allows them to handle the massive volume requirements of the Saudi Electricity Company (SEC) and STC.
