A plug-and-play fibre monitoring solution

SmartOTU is an easy-to-deploy, scalable solution that monitors fibres used in all types of optical networks. Maintaining fibre 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 fibre moves deeper into data centers and storage area networks. Combining a VIAVI Solutions® optical time domain reflectometer (OTDR) with advanced optical-switch technology, SmartOTU™ monitors fibres longer than 150 km in all directions. Modular in design, it monitors both dark and lit fibre and it is ideal for network security protection, pinpointing events such as fibre tapping to a few tenths of a decibel. SmartOTU is a standalone remote fibre test solution that can be deployed right out of the box with no training or IT configuration required.
