Test system for FTTH PON

Maestro FTTH test systems for FTTH PON access networks reduce costs of:

  • PON installation acceptance
  • Curative maintenance
  • Preventive maintenance
  • Proper customer provisioning (optical link checked beforehand)

Increase revenue from your fiber network:

  • Avoid customer churn by maintaining high service quality
  • Plan deployment of new services, GPON technology evolution, etc.


    Maestro FTTH user interface with graphical display for fault localization

    The Maestro FTTH test system is a centralized system controlling remote OTDRs and optical switches installed in central offices.

    Main features of the Maestro FTTH test system

    Curative maintenance

    • On-demand test in response to customer complaint to detect and localize fault

    Preventive maintenance

    • Detect troubles before customer complaints (cuts, stress, ageing, pollution on connectors, etc.)

    PON acceptance

    • Test application available on smartphone to check quality of installation (bad splice, pollution on connectors)
    • Centralized remote control of PON installation quality
    • Avoid reporting of field measurement to consolidate PON database

    Customer provisioning

    • Check fiber and loss before customer provisioning

    Database consolidation

    • PON database consolidated with measurement info (new events, ONT, length, loss*)
    • Database initialization / update from field measurement
(*) If calibrated reflection from ONT or external device
