VIAVI SmartOTU A plug-and-play fiber monitoring solution


is an easy-to-deploy, scalable solution that monitors fibers used in all types of optical networks.

Maintaining fiber integrity is critical, yet outages are still one of the major causes of network disruption, incurring millions of dollars of lost revenue. And, incidents of accidental dig-ups, vehicle collisions, and sabotage multiply as fiber moves deeper into data centers and storage area networks. 

Does not require any additional server or software applications — a simple web browser is enough to access all functionality including mapping. 

Displays the exact GPS location of a fault on widely-available, cloud-based mapping such as Google, Bing, or legacy GIS. SmartOTU is fully compatible with the VIAVI optical network monitoring system (ONMSi) and can be upgraded to be a comprehensive remote fiber test system as the network grows.
