VIAVI ONMSI

Smart fiber monitoring for a stable network

The VIAVI ONMSi Remote Fiber Test System (RFTS) is an intelligent monitoring and management solution designed to secure maximum fiber network uptime.

It proactively detects fiber degradation, accurately locates faults in real time, and provides complete visibility into network performance — ensuring stable and reliable connectivity.

By automating fault detection, diagnostics, and technician dispatch, ONMSi significantly improves operational efficiency and reduces MTTR from hours to minutes.

Long-term performance insights and accurate fiber records help operators plan smarter and protect their network assets.


Key benefits:

  • ONMSi performs automated 24/7 remote fiber testing for real-time fault detection, precise localization, and rapid restoration
  • Supports scalable architecture with distributed test probes for monitoring networks of any size
  • Enables comprehensive visibility and control of optical performance across P2P and P2MP topologies down to the ONT
  • Field-proven in more than 250 live networks ensuring high reliability and operational readiness
  • Integrates via web-based interface, APIs, and OSS protocols to streamline workflows, reduce MTTR, and enhance network resilience
