VIAVI OTU-5000 Optical Test Unit


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


  • Ensure continuously good service at construction, service activation and beyond

  • Anticipate service disruptions by detecting fiber degradation before it affects service.

  • Reduce MTTR by locating fiber optic faults in minutes instead of hours

  • Reduce operational costs by eliminating multiple erroneous dispatches

  • Protect investments by monitoring long-term fiber performance

  • Reduce construction costs by accelerating test processes and empowering test staff

  • Protect network integrity and security by detecting and locating fiber intrusion

  • Fiber monitoring for service providers, utilities, and dark-fiber providers

  • FTTx construction, provisioning, and maintenance tests

  • Fiber-tapping detection for critical applications

  • Infrastructure monitoring (manholes, cabinet, etc)

  • Switch scalability up to 1080 ports

  • Web-browser access

  • Advanced fault location

  • E-mail notifications

  • Small size: 72 ports in 1RU
