DWDM OTDR Module (4100-Series)

DWDM OTDR Module (4100-Series)

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, CellAdvisor 5G and OneAdvisor-800 platform testing features, ensures that comprehensive testing is done right the first time.
