Systems and methods for diagnosing anomalies occurring within a passive optical network via integrated domains
Techniques for diagnosing anomalies (e.g., faults, degradation and/or loss of service) occurring in a passive optical network (PON) include integrating, based on temporal precedence, real-time diagnostic information from multiple (and typically mutually-exclusive) domains of the PON into an integrated, multi-domain graphical view. The integrated, multi-domain graphical view may include a scrolling timeline and may organize alarm and other domain-specific events, environmental data, support information, and data from other domains to detect temporal correlations between events occurring in the different domains and thereby determine sources of anomalies occurring within the PON and initiate mitigating actions. Additionally, updating the view in real-time as additional diagnostic data is generated and integrating both real time and historical data from disparate domains results in more timely and accurate diagnosis of anomalies, identification of anomaly sources, and mitigation of (re-)occurring issues within the PON.
