OLT Monitoring Capabilities

NetSense provides comprehensive monitoring for all your optical line terminals. From hardware health to traffic analysis, get the visibility you need to run a reliable fiber network.

Hardware Monitoring

  • Temperature Monitoring

    Track OLT temperatures in real time. Get alerts before thermal issues cause failures.

  • CPU & Memory Usage

    Monitor resource utilization to identify overloaded devices and plan capacity.

  • Power Supply Status

    Track power supply health and get alerts on power-related anomalies.

  • Fan & Cooling Status

    Monitor cooling system performance to prevent heat-related failures.

  • Uptime Tracking

    Track device uptime and identify unexpected reboots or instability patterns.

Network Intelligence

  • PON Port Utilization

    Monitor bandwidth usage per PON port to optimize capacity distribution.

  • ONU Registration Status

    Track which ONUs are online, offline, or in error state across all OLTs.

  • Optical Signal Levels

    Monitor Rx/Tx power levels to detect fiber degradation before service impact.

  • Traffic Analysis

    Understand traffic patterns to identify congestion and plan upgrades.

  • Error Rate Monitoring

    Track FEC corrections and bit errors to catch fiber issues early.
