Situational Monitoring and Perimeter Protection Solutions

Based on Fiber Optic Cable

Based on Fiber Optic Cable

The system operation is based on the principle of coherent reflectometry. Optical pulses are repetitively sent into the monitored fiber, where a very small fraction of light is backscattered due to material non-uniformities. Fiber microdeformations caused by seismo-acoustic signals affect this backscattered signal. The signal changes are continuously monitored and analyzed to identify the location and specifics of the vibro-acoustic event detected by the fiber.

About the system

The system operation is based on the principle of coherent reflectometry. Optical pulses are sent into the fiber optic cable, and light is backscattered due to material non-uniformities. When the fiber undergoes microdeformations caused by vibrations or sounds, the backscattered signal changes. By analyzing these changes, the system identifies the precise location and characteristics of the impact. This allows for the detection of disturbance sources, such as the location of people, vehicles, or pipeline leaks.

K-DAS allows to detect various types of events throughout the fiber deployment zone with an accuracy of 10 meters including approach to the guarded zone, movement along the guarded zone, or trespassing the monitored zone border. Detection accuracy increases greatly if several adjacent monitoring zones can be arranged. Once a person or vehicle approach is detected, or if ground work in progress near the protected object is registered, K-DAS system immediately transmits an alarm message to the operator's computer indicating the source location. The system permits to detect any kind of activity that is causing water or soil vibrations. Installation of the system is customized, and Ksense specialists fine tune the system configuration taking into consideration the particular features of the deployment place and specific customer needs.

One of the main K-DAS applications is the development of early detection systems for critical infrastructure objects. Since acoustic sensor sensitivity permits to detect signals from sources located at dozens or even hundreds meters away from fiber, the system operator gets an alarm signal well before the trespassing.
K-DAS system is a 3U device unit to be installed in a telco rack. The unit has three slots for: receiver and transmitter board (coherent reflectometer), amplifier module, and industrial computer for data processing and transfer to a remote server. K-DAS system can be operated both as a stand alone unit and as a part of an integrated security system (API and Ethernet output are available).
