The Viavi OTU-5000 Optical Test Unit combines optical time-domain reflectometry (OTDR) and optical-switch technology to provide continuous OTDR monitoring of multiple fibres anywhere in the network. Designed for network operators and service providers, the OTU-5000 delivers automated, remote fibre monitoring in an exceptionally compact rack-mounted form factor — enabling faster fault detection, reduced operational costs, and proactive network maintenance.

The EOTDR2-L-A1-COTU module operates at 1625 nm out-of-band, making it suitable for monitoring live C+L band fibres without service disruption. A single OTU-5000 unit can monitor up to 72 fibres of 100 km and more within just 1RU of rack space.

The OTU-5000 is compatible with Viavi ONMSi and SmartOTU software applications, enabling rapid set-up and network-wide management of multiple OTUs concurrently.
