An overview of existing modern fiber-optic measurement systems (FOMS), which confirmed the relevance of the study in the world. It highlights the introduction of fiber-optic systems, distributed temperature and pressure gauges due to the highly informative indicators of pressure and temperature. The classification of the FOsensors(FOS) on the basis of their structural and physical properties, including the principles of coding of the measured data, the nature of the use of optical fibers. It is indicated that the type of FOS passing almost do not apply to high-channel connections. Instead, apply the FOSof antenna type in which information is generated optical radiation on the surface of the fiber. The FOS described by Fabry-Perot interferometer and a Mach-Zehnder interferometer. Presents approaches to the further development, taking into account the benefits of the three types of measurement procedures at the same time ( Rayleigh , Raman , Brillouin ).
