Complete visibility across your fiber infrastructure

Gain real-time insight into your network and resolve issues fast

Operational clarity across optical infrastructure

Reliable network operations depend on real‑time insight into fiber health to isolate faults quickly, validate performance and maintain consistent service assurance across fiber infrastructure.

Infrastructure monitoring provides continuous, in‑service visibility into the physical condition of optical fiber, empowering operators to isolate faults, validate performance and clearly separate infrastructure issues from active equipment failures. Our ALM fiber monitoring platform brings this physical‑layer insight to core, metro and access networks as a foundational operational capability.

As networks extend into more distributed and passive architectures, including FTTH, maintaining the same level of visibility becomes more complex. Adtran extends ALM monitoring beyond the splitter, using deep PON assurance and without requiring demarcation reflectors, enabling operators to apply a consistent monitoring approach across both active and passive fiber.

Paired with Mosaic and its GIS capabilities, data is correlated across network domains and mapped to precise physical locations. This gives operations teams clear root‑cause insight, reduces trial‑and‑error troubleshooting and enables faster, more accurate field dispatch across the entire fiber footprint.

Operational value and measurable impact

Infrastructure monitoring delivers tangible operational gains. It helps teams identify fiber issues faster and reduce time spent troubleshooting across passive and active networks by identifying fiber impairments in minutes instead of manual testing with expensive tools or field dispatch taking a lot of time. Real-time visibility enables proactive maintenance across the entire optical footprint. By correlating network signals and mapping them to precise physical locations, teams can resolve issues faster, reduce time per ticket and scale operations more efficiently while avoiding unnecessary truck rolls.

Solution brief

End‑to‑end infrastructure visibility has transformed how our customers’ teams operate. They identify issues faster, reduce unnecessary dispatches, and maintain service quality even as the network expands.
