8100-Series OTDR EVO Modules

8100-Series OTDR EVO Modules

The VIAVI Solutions® 8100-Series OTDR EVO family transforms fiber testing.
Connect the OTDR EVO family anywhere on the fiber to characterize single-mode and multimode fibers for commissioning, network upgrades, and troubleshooting with the added insurance of workflow optimization and accurate fiber-link fingerprinting.
The OTDR EVO family’s optical performance combined with the T-BERD/MTS platform’s complete suite of testing features ensures that testing jobs are performed right—the first time.


  • Up to 50 dB dynamic range
  • Integrated CW light source and broadband power meter (single-mode wavelengths)
  • PON-optimized to test through a 1×128 splitter
  • Single connector port for 1310, 1550, and in- service 1650 nm wavelengths
  • FiberComplete™ version available for automated bidirectional OTDR, IL, and ORL measurements
  • Built-in encircled flux multimode source compliant with IEC 61280-1-4 and TIA-526-14-B
  • Industry-leading dead zone performance for full element event characterization on fiber links 2 m apart
  • Includes an integrated power meter, light source, and OTDR in a one-port tool for added flexibility
  • Instantaneous, automatic traffic detection avoids risking live signal interference or optical transmitter damage during an OTDR test
  • Eliminates OTDR interpretation errors with Smart Link Mapper (SLM) without compromising on test time
  • Reduces event loss measurement uncertainty and improves measurement repeatability
