Passive Optical Networks Monitoring

Passive Optical Network Monitoring

Passive Optical Network (PON) monitoring gives operators the ability to track, isolate, test and troubleshoot an entire fiber network—even before it’s turned up and handling live customer traffic.

PON monitoring saves substantial time (up to a 50% reduction in mean time to repair) and capital expenses (up to 70%) during:

  • Initial fiber plant construction
  • Fiber-to-the-home (FTTH) network deployments for single-family dwellings and multiple-density units
  • Network operations, maintenance and any necessary field services

PON Monitoring: The Basics

PON Fiber Monitoring uses non-disruptive OTDR technology to acquire the backscatter and reflection signatures from the network up to the individual ONTs using very short pulse-widths of light. The shorter the pulse of light used for probing the network, the higher the detection resolution becomes. Utilizing a complex PON analysis algorithm, a service provider is able to disentangle each individual fiber's contribution from the composite trace. Continuous trace monitoring rapidly identifies discrepancies from the reference trace and issues an alarm to dispatch the correct team to resolve the event. This method has proven effective in distinguishing between subscribers with fiber length differences of around 1 meter. Reflectors can also be used to enhance the visibility of Optical Network Terminals (ONT) under high-noise or low resolution conditions.

Thanks to an advanced PON analysis algorithm built-in to the NTest solution, service providers can disentangle individual fibers contribution from the composite trace. Continuous trace monitoring rapidly identifies discrepancies from a reference trace and issues an alarm to dispatch the correct team to resolve the event, deliver maximum customer uptime and protect SLAs.
