VIAVI OTDR Module 8100 Series


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

  • Up to 50 dB dynamic range and 256,000 acquisition points

  • ≤ 65 cm Event Dead Zone and 2.5m Attenuation Dead Zone

  • Integrated CW light source and broadband power meter on OTDR port (singlemode wavelengths)

  • PON optimized to test up to 1x128 splitter type

  • Combined singlemode/multimode version

  • Single-/Dual-/Tri-wavelength versions with 1310, 1490,1550,1625, and 1650nm
