The T-BERD®/MTS-8000 DTSS distributed fibre optic solution is used for measuring temperature and strain using single ended Brillouin OTDR.

Based on Brillouin scattering technology, Viavi BOTDR module measures the temperature and strain along an optical fibre cable. The BOTDR module can be set up in portable platform (T-BERD/MTS-8000) for cable commissioning and routine auditing or in rackable platform (OTU-8000) for permanent monitoring through the most widely deployed fibre monitoring system, the ONMSi.


  • Fibre characterisation with B-OTDR reveals fibre strain and elongation or temperature
  • Ensure installations are done correctly without strain
  • Reduce and reverse cable strain by locating and releasing it before it breaks the cable or reduces the cable life using the portable DTSS


  • Pipeline monitoring
  • Telecommunications cable strain testing for manufacturing, installation and maintenance
  • Power cable monitoring
  • Structural Health Monitoring (SHM)

CoverTel Participates in the Australian Oil and Gas Show

In mid-March, the Australian Oil and Gas (AOG) Show was held in Perth.

CoverTel Telecommunications Group, along with their Prime Principal VIAVI, were there to display a number of items including the VIAVI DTSS (Distributed Temperature and Strain Sensing) Fibre Monitoring system.

The OTU 8000 modular rack-mounted, automated OTDR test unit makes traditional OTDR traces, as well as DTS and DTSS (Distributed Temperature and Strain) Measurements.

For more information on the VIAVI DTSS Fibre Monitoring System or any other VIAVI product please call the experts at CoverTel on 1800 268 378.
