Electric power utilities rely on extensive fiber networks for critical grid functions such as tele‑protection, equipment monitoring, and data acquisition. Any fiber damage can threaten grid reliability, making rapid fault detection and recovery essential. VIAVI’s ONMSi provides remote fiber testing and monitoring to quickly identify, diagnose, and locate faults, helping operators maintain resilient communications. With security also a major concern—since inexpensive taps can access all in‑flight data—utilities benefit from continuous monitoring to protect infrastructure and ensure fast restoration when issues occur.
