At the near end of the optic fibre transmission line, an optical sounding pulse pattern is entered in the fibre optic. The Rayleigh back scattering signal received from the optic fibre at the near end is applied to the input of an optic radiation polarisation analyzer. At the output, the power of single polarisation optic radiation is received and the back scattering characteristic is measured. The sounding pulse length is set several times more than the beat length. Previously, the measured back scattering characteristic is converted so as to suppress distortions due to the form and final length of the sounding pulses. The periodic component is extracted and divided into elementary sections, and the beat length is determined for each elementary section, as half of the component period.
