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.
