System for identifying source of degradation in passive optical network
A recently granted patent (Publication Number: US11863919B1) discloses a system for identifying the source of degradation within a passive optical network (PON). The system includes processors and memories storing computer-executable instructions that detect whether an optical line terminal (OLT) or a first optical fiber is the source of degradation based on differences in optical profiles within the PON. If the differences are within predefined tolerances, the system identifies the source as the OLT; otherwise, it points to the last mile termination unit or a second optical fiber. The system provides an indication of the detected source to a recipient application or device, enhancing network maintenance and troubleshooting capabilities.
Furthermore, the system can determine the optical profile of a segment based on characteristics of optical signals, such as attenuation or changes in frequencies or power outputs. It can also predict a time-to-failure of the identified source of degradation. The method can be executed by processors on servers within the PON or on portable computing devices associated with the network. By efficiently pinpointing sources of degradation within the PON, this patented system offers a valuable tool for maintaining and optimizing the performance of optical networks, ensuring reliable and efficient service delivery to end-users.
