    VIAVI 4100-Series CWDM OTDR Modules

    For T-BERD®/MTS-2000, −4000, −5800 Platforms

    Connect the VIAVI Solutions™ 4100-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.

    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


    • 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


    • 8 or 10 CWDM wavelengths in 1 module and 18 wavelengths in 2 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

    Moduły OTDR CWDM z serii 4100 to idealny wybór dla utrzymania i rozwoju sieci C-RAN, DAS, CWDM.
