The paper presents the creation results of the optical low-coherent reflectometer based on spectral interferometry with a heterodyne frequency transfer into the radiorange that allows to measure distances of tens of kilometers. The reflectometer layout for micro-distances based on fiber-optic Fabry-Perot interferometer and broadband infrared source was designed, fabricated and tested. Based on these investigations the feasibility and advisability of using the low-coherence spectral interferometry method for reflectometry measurements of distances for fiber-optic communication lines was demonstrated.
