Vláknová infrastruktura je naprosto esenciální pro většinu přenosů informace na větší vzdálenosti. Vláknová infrastruktura je ale velmi často ohrožována, jak při stavebních pracích (např. nekázní, chybami), ale také krádežemi vedení. Vlákna samotná lze ale použít přímo tak, že se stávají distribuovaným senzorem. Při vhodných konfiguracích mohou vlákna sloužit stále k primárnímu účelu, tedy k přenosu dat a není nutné vyhrazovat zvláštní vlákna pro snímání anomálií.

Description in English
Fiber infrastructure is absolutely essential for the vast majority of traffic information over long distances. This obviously applies to communications of government, research organizations, banks, security forces or hospitals. In other cases, it is alsoa critical communication, such as management or security. Also, most phone calls, including mobile call transmissions over greater distances runs over optical fibers. Fiber infrastructure is often threatened both during construction work (eg. mistakes),but also thefts. The fibers themselves may be used directly as a distributed sensor, and can also be used to detect anomalies accompanied by vibrations. Thus, the aim of the project is to design and implement a security system where, at the appropriateconfigurations, fibers can still serve the primary purpose, namely to transfer data, and it is not necessary to reserve special fibers for sensing anomalies. Outside the necessary functions for communicating government is thus possible to capture anomalies of other critical infrastructures such as conductor EHV lines, along pipelines or in embankments of railway lines or highways. The new system will help to increase the security of critical infrastructures. Thanks to early detection of potential disruptions of a fiber infrastructure threats can be averted, thereby enhancing the protection of data infrastructures.
