VIAVI NITRO AIOps PON Assurance Multivendor PON Assurance Platform

The passive section of a PON between the OLT and the subscriber generates no telemetry. When a splitter or fiber span degrades, element management systems may show no alarm, and the first indication is often a subscriber complaint.

VIAVI NITRO AIOps PON Assurance scores every element across the PON network, both active and passive and from any vendor, to detect degradation hours before subscribers notice and to initiate resolution automatically. VIAVI describes it as the only platform that combines physical-layer fiber monitoring with AI-driven assurance in a single, telco-grade view.

QoE Detection

The QoE engine scores every element in the PON hierarchy, including splitters, distribution fiber and drop fiber that generate no alarms. Intermittent degradation and early-stage impairments are surfaced hours before they become outages.

Integrated Automation

Analysis of a complex PON fault, which according to VIAVI typically takes an experienced engineer 90 minutes of cross-system work, is performed in seconds: blast radius, correlated data, a fully enriched ticket and a crew assigned to the precise network segment. OTDR-based fiber monitoring closes the diagnostic gap that leads to the wrong team being dispatched and second truck rolls. VIAVI states that resolution times drop by 75%.

PON AI Expert and Multivendor OLT Assurance

The PON AI Expert answers engineer queries using inventory, topology, fault and performance data in a single response, and generates documentation, tickets and handover notes automatically. The platform supports multiple OLT vendors, with Nokia, Huawei, ZTE and Calix correlated in one view with normalized KPIs and consistent alarm handling; VIAVI states that NOC vendor specialist dependency drops by 33%.
