    Opis produktu VIAVI OTDR Modules 4100-Series


    4100-Series DWDM OTDR Module

    For T-BERD®/MTS-2000, -4000 V2, -5800 Platforms

    As xWDM technology adoption continues to grow in access networks for broadband services, technicians require comprehensive and lightweight xWDM test tools. Consisting of a single module, the VIAVI C-band DWDM OTDR solution enables cable, wireless, and telco operators to perform complete end-to-end link characterization and troubleshooting of DWDM and hybrid CWDM/DWDM networks.

    The DWDM OTDR module’s optical performance, combined with the complete suite of T-BERD/MTS platform testing features, ensures that comprehensive testing is done right the first time.

    Standard testing features include:

    • Auto-setting of the acquisition parameters
    • Summary results table with pass/fail analysis per the international standards
    • Comprehensive event diagnosis
    • FastReport onboard report generation

    Key Benefits

    • Characterize fiber links with exact DWDM wavelengths
    • Troubleshoot live networks with in- service testing capability
    • Verify end-to-end continuity through MUX/DEMUX and ROADMs using the continuous wave source function
    • Smart Link Mapper (SLM) eliminates OTDR interpretation errors without impacting test times

    Key Features

    • Tunable DWDM OTDR module at ITU-T

    G.694.1 wavelengths

    • C-band - 1528 nm to 1568 nm
    • 44 dB dynamic range for access and metro applications
    • Integrated CW light source with modulation capability
    • Instantaneous traffic detection


    • Metro & access rings, business to business, advanced C-RAN fronthauls & next gen FTTH networks
    • Qualification of fronthaul access networks
    • Testing new DWDM wavelength routes without disrupting traffic on active channels
    • Pinpointing faults and their exact locations while in service

    Moduły OTDR z serii 4100 to wydajne rozwiązanie, które w połączeniu z szerokim zakresem funkcji pomiarowych platformy MTS idealnie dopasowuje się do wyzwań jakie stawiają sieci optyczne w dowolnej architekturze.
