OTDR Modules – 8100-Series for T-BERD/MTS-6000A, -8000 Platforms

VIAVI 8100-Series OTDR EVO family includes the “8100A”, “8100B”, the “8100C”, and the “8100D” modules for any singlemode or multimode OTDR application and test scenario from very short to ultra-long distances. Learn more about OTDR Testing and Fiber Testing.

The optical performances of the 8100-Series OTDR modules combined with the complete suite of T-BERD/MTS platforms testing features ensure that any testing job is done right the first time.


  • Industry leading dead zone performance which allows full characterization of element events on a fiber link 2 meters apart (EVO family).
  • Combines OTDR, power meter and continuous light source for added testing flexibility (singlemode wavelengths).
  • Avoids the risk of live signal interference or damage to the optical transmitter when performing an OTDR test with instantaneous automatic traffic detection.
  • Eliminates OTDR interpretation errors with Smart Link Mapper (SLM) without compromising on test time.


  • Access, Metro, Long Haul and Ultra Long Haul fiber network characterization.
  • Tier 2 certification of enterprise and data center networks.
  • Advanced qualification and troubleshooting of FTTH/PON networks.
  • Core fiber network upgrade to 40 and 100Gb/s.
  • Fiber Monitoring in and out-of-service.
  • Fiber installation/deployment certification and troubleshooting for Submarine Cable Networks.
