Active Optical Network and Passive Optical Network Fiber to the home (FTTH) enables the installation of fiber directly from the central point to the end user's home, providing unprecedented high-speed Internet access. There are two types of technologies for implementing FTTH network: AON (active optical network) and PON (passive optical network). What is AON? AON is an Active Optical Network, which mainly uses a point-to-point (PTP) network architecture, and each user can have a dedicated optical fiber line. Active optical network means that during the transmission of signals, switching equipment such as routers and switching aggregators, active optical devices, etc. are deployed from the central office to the user distribution unit. These switching equipment are driven by electricity to manage Signal distribution and direction signals for specific customers. Active optical devices include light sources (lasers), optical receivers, optical transceiver modules, optical amplifiers (fiber amplifiers and semiconductor optical amplifiers), etc.
What is PON? PON is Passive Optical Network, a point-to-multipoint network structure,
