Abstract. The possibility of using single-mode optical fiber applied in telecommunications to create a liquid boiling alarm is investigated. It is established that when the temperature of liquid boiling is reached, the coefficient of optical radiation reflection by the interface of two media — the fiber core and the liquid — changes. As a result, the power of optical signal reflected back into the fiber from the interface of such media increases. An increase in the power of the reflected signal to a certain value indicates that the boiling point of the liquid has been reached. It is shown that the difference between the attenuation value on the reflectometer scale at the maximum point for the peak of the reflectogram of a single-mode telecommunication optical fiber and the attenuation value on the reflectometer scale before the peak of this reflectogram can be used as an information parameter for determining the moment of reaching the boiling point.
