The basis of this work is the results of research on the development of the method of
detection and localization of the site of unauthorized access for the fiber-optic
communication line.
We studied functioning of the fiber-optic line in emergency
conditions
.
On the basis of analytical review of methods of unauthorized access to the
optical fiber we propose a developed method of detection and localization of the site of
leakage radiation from the optical fiber
. The method consists in applying a laser phase
rangefinder as a device for monitoring the information security. It is shown that
application of classical laser phase rangefinders allows to achieve localization accuracy
up to several centimeters.
Keywords:
optical fiber, radiation leakage, monitoring, information security, laser
rangefinder.
