Gigabit Passive Optical Network (GPON) is a network infrastructure that utilizes passive optical components for fast and efficient data transmission. It consists of an Optical Line Terminal (OLT) and Optical Network Units (ONU). It employs passive splitters to distribute signals to multiple users via optical fibers, providing gigabit data transmission speeds. GPON is commonly used in access networks, particularly in Fiber-to-the-Home (FTTH) implementations. GPON technology plays a crucial role in delivering stable and high-speed broadband data transmission.
