XPON is a dual-mode PON solution that supports both GPON and EPON on a single device through automatic detection. It allows an ONU or ONT to automatically detect and adapt to the upstream OLT standard, enabling seamless interoperability in hybrid networks. It supports diverse applications such as FTTH, smart cities, 5G backhaul, and industrial IoT by providing. This integration allows multiple wavelengths to transmit data over a single fiber, significantly enhancing efficiency. Passive Optical Network (PON) is a point-to-multipoint passive optical access network that consists of an OLT (Optical Line Terminal), ODN (Optical Distribution Network), and ONU/ ONT (Optical Network Unit/Terminal). Currently, PON technology has evolved from APON to the most mainstream EPON/ GPON. Among the most established standards are GPON and EPON, each with distinct technical architectures and deployment.
