BOTDR – Brillouin Reflectometer

BOTDR: Brillouin OTDR Fiber Sensor Technology on the Measurement of Temperature and Stress

Viavi’s BOTDR modules use Brillouin scattering to accurately measure temperature and stress along a fiber optic cable. Even over long distances, temperature differences and stress on the fiber can be localized with a resolution of a few meters. The OTU-8000 rack can be used for permanent real-time monitoring and integrated into an ONMSi system. This makes the BOTDR the ideal addition to the spatially-resolved control of KRITIS monitoring systems. In addition to the rack version, a BOTDR module is offered that can be integrated into the mobile MTS-8000 platform.

BOTDR in KRITIS Monitoring

As part of an OTU-8000 or a comprehensive ONMSi system, BOTDR measurement is a welcome addition to the control of critical infrastructures. A single fiber for the test signal is sufficient to monitor the entire cable over long distances (up to 200 km).

Possible Applications:

• Pipelines
• Telecommunication
• Power cables
• Building surveillance

Mobile Solution: BOTDR in MTS-8000

As part of the MTS-8000 modular multi-test platform, the BOTDR solution offers additional measurement options for setting up and maintaining high-speed networks. The technician can check cables with lengths between 100 m and 200 km on site. For distances of up to 10 km, changes in temperature and stress can be located precisely to the meter.

Advantages:

• Simultaneous measurement of stress and temperature
• Single-ended
• Measurement on just one fiber
• Compact, modular, and lightweight
• BOTDR surveillance
