EPON (Ethernet Passive Optical Network) is a type of fiber optic network technology that is used for delivering broadband internet access and other high-speed data services. It uses a point-to-multipoint architecture, where a single optical fiber is shared among multiple subscribers through an optical splitter. The technology is based on the Ethernet standard, which makes it compatible with existing Ethernet-based networks. EPON supports symmetric bandwidth, which means that the upload and download speeds are the same, making it ideal for applications such as video conferencing, online gaming, and cloud computing. EPON is a popular choice for service providers due to its high bandwidth capacity, low cost, and ability to support large numbers of subscribers.
