Enhanced multi-branch sensing by leveraging the Fresnel reflection points in phase-sensitive OTDR-based PON monitoring

We achieve distributed sensing of the feeder link in passive optical networks employing a phase-sensitive optical time-domain reflectometer, while enhancing event monitoring by leveraging Fresnel reflections from fiber connectors in multiple branches to detect temperature changes, vibrations, breakpoints, and bends.
