Optical Line Terminal (OLT) Core of Optical Access Network

OLT is the central office equipment in optical access networks, connecting to metro or backbone networks and providing data aggregation, forwarding, and management for multiple Optical Network Units (ONUs). It transmits downstream data to ONUs via optical fibers and receives upstream data, enabling efficient optical communication. Indispensable in broadband access scenarios like FTTH (Fiber to the Home) and FTTB (Fiber to the Building), OLT ensures high-speed and stable broadband access services for users.
