The OTU-5000 Optical Test Unit combines optical time-domain reflectometry (OTDR) and optical-switch technology to provide continuous OTDR monitoring of multiple fibers anywhere in the network. A single OTU-5000 unit monitoring 72 fibers of 100km and more occupies only 1RU. Learn more about OTDR Testing and Fiber Testing.

The OTU-5000 works with the VIAVI ONMSi solution to help automate and improve the monitoring of your network performance.

VIAVI is the worldwide leader in OTDR manufacturing and Optical Network Monitoring, receiving the coveted Frost & Sullivan Fiber Optics Test Equipment Market Leader Award for fiber-optic test equipment six years in a row.
