An optical distribution network (ODN) mainly has primary splitting and secondary splitting, or centralized splitting and cascade splitting. When you stream a 4K video, join a remote meeting, or play an online game on a gigabit fiber connection, an OLT. The OLT communicates with the optical network unit (ONU) or optical network terminal (ONT) at the user end, coordinating the distribution of data and ensuring that each connected user receives the appropriate information. Equipment Components Generally speaking, OLT equipment includes a rack. A splitter takes a single beam of light from the OLT and splits it into multiple beams (e., 1:32 or 1:64) to serve multiple homes, eliminating the need to run a dedicated fiber from the ISP to every single house. Point-to-multipoint architecture. Only at the. In the backbone of modern Fiber-to-the-Home (FTTH) networks, optical splitters serve as the unsung heroes that enable cost-efficient connectivity for millions of subscribers.
