From their conception, optical fibers have been primarily used in telecommunications technology to transmit data using non-polarized light. Nowadays, however, the development of fibers has advanced considerably and new applications have been discovered. One such application is utilizing optical fibers as sensors, predominantly polarizing fiber sensors working with polarization-preserving fibers. Their use thus extends to the temperature/pressure sensor used in this work. This article deals with the issue of temperature measurement using a single- mode sensory polarization maintaining fiber. Since this fiber is not circularly symmetrical, or rather, the stress elements inserted into this fiber are utilized, birefringence occurs in its core. With the help of this birefringence, it is then possible to monitor the mutual displacement of the two axes and to measure changes in the ambient temperature of the sensor fiber. Problems occur with sensors that need to be supplied with light over long distances using common communication fibers. This option is very beneficial especially in potentially explosive atmospheres and in general in places where an electrical signal cannot be applied, for example, due to neutral EMC compatibility.
