VIAVI DAS fiber optic sensing
– Intelligent border protection

Continuous monitoring.
Early detection.
Improved situational awareness.
 

Protecting national borders requires reliable monitoring across large, remote and often difficult-to-access areas. Traditional surveillance cameras and physical patrols can have limitations in these environments. Distributed fiber optic sensing provides an additional layer of security by detecting activity along extensive sections of protected infrastructure.

VIAVI's Distributed Acoustic Sensing (DAS) technology transforms an optical fiber into a continuous sensing system capable of detecting vibrations and acoustic disturbances along a monitored route. This gives security personnel valuable information about activity near border fences, security perimeters and other protected areas.

Turning optical fiber into a security sensor

DAS technology works by analyzing changes in light backscattered through an optical fiber. These changes can reveal vibrations caused by footsteps, vehicle movement, interference with fencing or other activity near the monitored infrastructure.

Advanced signal processing helps distinguish between different types of events, allowing operators to identify activity that may require further investigation.

One of the main advantages of DAS is its ability to monitor long distances using a single optical fiber, without installing individual electronic sensors at regular intervals along the route.

Key benefits
for border protection

Continuous perimeter monitoring

Optical fibers can provide continuous sensing coverage along extensive border sections, security fences and other protected areas.
 

Early detection of potential threats

By detecting characteristic vibrations and acoustic events, DAS can provide early warning of potential perimeter breaches, allowing security personnel to investigate and respond more quickly.
 

Integration with existing security systems

Depending on the system configuration, DAS can be integrated with surveillance cameras, security management platforms and central control rooms. Combining information from multiple systems helps operators assess events and verify alarms.
 

Suitable for remote and challenging environments

Fiber optic sensing is particularly useful across long or remote sections where installing and maintaining large numbers of individual electronic sensors would be difficult. System performance depends on factors such as cable installation, environmental conditions and system configuration.
 

Improved situational awareness

Detected events can be displayed and analyzed at a central operator workstation, providing security personnel with a clearer overview of activity along the monitored route. This supports informed decisions about further investigation and the deployment of patrols.

A layered approach to border security

Distributed Acoustic Sensing is most effective as part of a broader, multi-layered security system. Combining DAS with video surveillance, communication networks and established security procedures provides a more complete picture of activity along protected borders.

While DAS detects and helps locate unusual activity along the fiber route, cameras and security patrols can be used to verify the cause. This approach helps security personnel focus their resources where they are needed most, reducing the need for continuous visual monitoring of every section.

To maintain reliable performance, the system must be properly configured and regularly evaluated. Appropriate event classification, false alarm management, secure system integration and routine maintenance are important for effective long-term operation.
