Optical Test Unit


Automate optical network monitoring with the most compact rack mounted, remote OTDR test unit on the market!

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.


  • Switch scalability up to 1080 ports
  • Web-browser access
  • E-mail notifications
  • Small size: 72 ports in 1RU
  • Dual power feeds
  • Solid-state disk
  • Low power consumption
  • LAN-based firmware downloads

Key Benefits

  • 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 longterm 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, data centers, utilities, and dark-fiber providers
  • FTTx construction, provisioning, and maintenance tests
  • Fiber-tapping detection for critical applications
  • Infrastructure monitoring (manholes, cabinets, etc)
