Network Analyzer - Fiber

Ensure that the PON and optical links meet QoS requirements for best broadband customer experience of successful fiber-to-the-home services deployment

The Network Analyzer – Fiber (NA-F) helps service providers ensure that the passive optical network (PON) links meet quality of service (QoS) requirements for the successful deployment of high-bandwidth services over a GPON and NGPON-2 fiber access network.

The NA-F monitors the PON and optical link lifecycles from initial documentation to activation, operations and customer support. In each phase, you can view insights on the equipment state, subscriber impact and faults present.

With NA-F you can minimize the number of degradations to prevent service failures where possible and repair faults quickly and predictably when they occur. It provides unique diagnostic and enhanced fault localization capabilities that enables the identification of root causes for issues, dramatically reducing the time and resources required for fault identification and resolution.

The NA-F is a key part of our home and access analytics portfolio. By offering a reporting feed to the Nokia Care and Provisioning portfolio you gain access to the right insights and recommendations as needed – operations, field, assisted and self-care – so that you can accelerate service activation, boost first-call resolution (FCR) rates and reduce average handle time (AHT) for optical link-related issues. This improves QoS, enhances the customer experience and reduces churn while increasing the likelihood of selling higher bandwidth services.


  • Accelerate time-to-market by minimizing OSS/network misalignments, and power drop of new ONT installs during drop activation (vertical fiber build-out and ONT subscriber activation) to avoid late notice, wrong dispatches and SLA penalties
  • Reduce CAPEX associated with returns of non-faulty ONTs and avoid additional CAPEX related to test heads, probes or handheld meters by leveraging existing access equipment measurement capabilities
  • Reduce OPEX by minimizing the number of degradations to prevent service failures where possible and repair faults quickly and predictably when they occur
  • Decrease churn when side effects for subscribers and neighboring links are avoided, and help with GPON capacity growth to meet user demand for heavy PON users
  • Provide a better customer experience through efficient agent-assisted care, field service and self-care for ONT installation


  • Optical power drops for 4% of new ONTs in first 30 days after installation
  • 80% of customer calls related to HD video failures caused by physical issues before customers notice service quality degradation
  • 27% of truck rolls related to accidental impacts to neighbouring subscribers on the same passive optical network (PON) during repair activities
  • 6% of fiber failures directly related to dirty or loose connectors
  • ONT software version issues are responsible for 15% of help desk calls
  • 27% of GPON repairs fail to deliver QoS
