Operators of infrastructure networks are often responsible for hundreds or even thousands of distributed sites. Utility manholes, technical cabinets, access points, and other critical facilities are spread across a vast area, making constant physical inspection generally impractical. At the same time, there is a growing need to gain a quick overview of what is happening at a site — even when it is located tens of kilometers away.
How can one find out if someone gains access to the site?
But how can you find out if someone gains access to an asset that isn’t monitored on a daily basis? To address this, Gridstock has added the SAFIBRA fiber-optic monitoring system to its product range; it enables the monitoring of utility manholes, technical cabinets, entry points, and shafts, allowing for the detection of potential intrusion or vandalism attempts at an early stage.
Fiber-optic monitoring without on-site power supply
One of the greatest advantages of this solution is the ability to utilize an existing fiber-optic network. The connection between the sensors and the central monitoring unit is established via standard optical fibers, and no electrical power supply is required at the monitoring points. This enables the monitoring of assets even in locations where implementing traditional solutions might be difficult or where there is no power supply.
The system operates based on Fiber Bragg Grating (FBG) technology, which enables the detection of physical changes and disturbances with high precision. The solution is passive, immune to electromagnetic interference, and suitable for use in complex or hard-to-reach environments. Furthermore, the system can monitor up to 640 FBG sensors simultaneously and send alerts immediately upon the detection of anomalies or potential interference.
Real-world use cases from Europe
Although the use of such solutions is still growing in Estonia, SAFIBRA fiber-optic monitoring systems have already been implemented in various infrastructure and security projects. These include, for example, real-time monitoring of railway tunnels in Austria, the surveillance of railway bridges, and projects for detecting vandalism and intrusion attempts—scenarios where the solutions function even over long distances without the need for a local power supply.
Physical security as part of modern infrastructure protection
Physical security no longer means just locks, fences, or periodic patrols. Knowing what is happening at a site in real time is becoming increasingly important. The faster information about a potential intrusion reaches the person in charge, the better they can assess the situation and, if necessary, take action.
There is increasing talk about cybersecurity, yet for many infrastructure facilities, security actually begins with the control of physical access. The question is no longer just whether a facility is protected, but rather how quickly you are notified if someone gains access to it.
