GPON, or Gigabit Passive Optical Network, is a fiber-optic technology standard for delivering high-speed internet, TV, and voice services (triple-play) using a point-to-multipoint architecture, sharing a single fiber among multiple users via passive splitters for cost-efficiency. It offers speeds up to 2.5 Gbps downstream and 1.25 Gbps upstream, making it a popular choice for Fiber-to-the-Home (FTTH) and Fiber-to-the-Premises (FTTP) networks by connecting central Optical Line Terminals (OLTs) to customer Optical Network Terminals (ONTs/ONUs).
Key Aspects:
"Gigabit": Refers to its high data transmission speeds (Gbps).
"Passive": Means it uses passive optical splitters in the distribution network (ODN), which don't need power, reducing costs and complexity compared to active networks.
Architecture: A single fiber from the OLT splits to serve many users (e.g., 1:32 or 1:64 split), efficiently sharing bandwidth.
Services: Delivers data (Ethernet), voice (VoIP), and video over fiber, known as "triple-play".
Standards: Defined by the ITU-T G.984 series of standards.

OLT, or Optical Line Terminal, is the central device in a fiber-optic network (like PON) that connects the service provider's core network to multiple customer locations, managing and distributing high-speed internet, voice, and video services using optical signals, essentially acting as the "brain" for delivering fiber to homes (FTTH). It converts electrical signals to optical signals for transmission over fiber, manages traffic, and controls end-user devices (ONTs/ONUs).
