A Point-to-Multipoint (P2MP) All-Optical Network (AON) is a communication architecture where a single central node (e.g., an Optical Line Terminal, OLT) connects to multiple remote nodes (e.g., Optical Network Units, ONUs) using optical fiber. This architecture is highly efficient for scenarios requiring high bandwidth, low latency, and scalability, such as broadband access, smart cities, and industrial IoT.
