Viavi Introduces 18-Wavelength OTDR, the most compact and affordable solution on the market to turn up and certify CWDM networks

New OTDR helps increase efficiency in CWDM network deployment and troubleshooting

October 24, 2016 — Viavi today introduced the 4100-series CWDM OTDR for its T-BERD/MTS-2000, 4000, and 5800 platforms, making it the most compact and affordable solution on the market to turn up and certify CWDM networks.


  • Test new CWDM wavelength routes without disrupting traffic on active channels to pinpoint exact fault locations
  • Prove end-to-end continuity and continuous wave-source function (included standard at each CWDM wavelength)
  • Work with a comprehensive solution in qualification and troubleshooting for field technicians when combined with Viavi’s CWDM spectrum analyzer
  • Simple add-on to existing fiber/Ethernet test tools

Use Case:

The 4100-series CWDM OTDR is designed for wireless operators deploying active C-RAN and DAS networks or business service providers requiring a combined fiber/Ethernet qualification solution for high quality networks. Combined with the Viavi T-BERD®/MTS-5800, these new OTDR modules enable physical-layer fiber certification and troubleshooting along with CPRI, OBSAI and Ethernet service tests in a compact test platform. To ensure SLA compliance from day one, users will be able to validate all 18 CWDM wavelengths and prove Ethernet service from 10Mb/s to 100Gb/s.

Viavi is the worldwide leader in OTDR manufacturing and has been awarded the coveted Frost & Sullivan Fiber Optics Test Equipment Market Leader Award for fiber-optic test equipment for four years in a row.
