Brillouin scattering can be used to detect temperature differences and strain in optical networks, even over long distances, and localize them to within a few meters. Viavi Solutions is the only manufacturer to have developed BOTDR measuring devices that can even distinguish which of the two factors caused the change in the optical signal.
For example, when monitoring district heating pipelines, it is possible to determine whether a fault is due to temperature changes or mechanical influences. The system can also be used to monitor gas pipelines, overhead lines, or bridges. A single fiber is sufficient to monitor distances of up to 200 km.
Viavi Solutions offers two versions of its BOTDR measuring devices: The OTU-8000 is designed for stationary use in a control cabinet. As part of an ONMSi solution, the Brillouin measurement can be combined with other methods. This ensures comprehensive 24-hour monitoring of critical infrastructures. The portable version can be integrated into the MTS-8000 system and offers a technician a wide range of measurement options on site.
