FIELD: instrument making.
SUBSTANCE: invention relates to the methods of optical fiber (OF) continuous control and may be used as an algorithm for the software within the protection system controller of FOTS for restricted information. Method of disordered optical fiber continuous control comprises recept, detection of optical signals from a fiber optic line, amplification, integration and analog-to-digital conversion of the received analog electric signals. Before control, define the number of observation readings N, current yj and previous yj-1 values of average sample values for N readings from formula:
EFFECT: obtained technical result is correlation of the observation time with the start of disorder signal and optimal choice of observation time.
