Anomaly detection in passive optical networks using light signals
The patent US12028108B1 outlines a method and computing device for detecting anomalies in a Passive Optical Network (PON) through light level detection. The method involves generating optical profiles for both the PON and individual customers based on characteristics of light level signals collected over a specified time period. Key characteristics include mean light levels, standard deviations, and slopes of the signals. By comparing customer light level signals collected during a subsequent time period against these established profiles, the method identifies anomalies when deviations exceed a predetermined threshold. Additionally, the system can provide notifications of detected anomalies to users or other computing devices.
Further enhancements to the method include the ability to automatically reboot PON components in response to detected anomalies and perform root cause analyses to identify the origins of these anomalies based on customer locations. The detection process may utilize Z-scores to quantify deviations and assess trends in light level signals over time. The computing device is equipped with processors and memory to execute these functions, including the generation of trend, seasonality, and residual components of the light level signals. This comprehensive approach aims to ensure the reliability and performance of PON systems by proactively identifying and addressing potential issues.
