for MTS-2000, -4000, -5800 devices
Connect the Viavi Solutions™ -Series CWDM OTDR family to successfully deploy and maintain C-RAN, DAS, CWDM, and fronthaul networks. CWDM OTDR-family optical performance, combined with the T-BERD/MTS platform’s suite of testing features, ensures that testing jobs are performed right—the first time.


  • Characterize fiber links with exact CWDM wavelengths
  • Qualify C-RAN, DAS, and any mobile fronthaul network
  • Troubleshoot live networks with in-service testing capability
  • Verify end-to-end continuity using the continuous wave source function
  • Eliminate OTDR interpretation errors with Smart Link Mapper (SLM) without comprising test times

Key Features

  • 18 CWDM wavelengths in only 2 OTDR modules
  • Optimized performance for access and metro applications
  • Integrated CW light source with modulation capability
  • Instantaneous traffic detection


  • Qualification of fronthaul access networks
  • Testing new CWDM wavelength routes without disrupting traffic on active channels
  • Pinpointing faults and their exact locations while in service

Testing features include

  • Automatic multitest configurations
  • Easy-to-read summary results table with pass/fail analysis
  • Quick trace interpretation with SLM (optional)
  • FastReport™ onboard report generation
