This splits the fiber out to individual customer locations, creating a tree network topology. OLT belongs to the business node side of the access network equipment, connected to the corresponding business node equipment through the SNI interface, to complete the access network service access. Connected with the front-end (convergence layer) switch with a network cable, converted into. By dividing a single optical signal from a central Optical Line Terminal (OLT) into multiple outputs for Optical Network Terminals (ONTs) at users' homes, splitters eliminate the need for dedicated fibers to each residence—slashing infrastructure costs while scaling network reach. The splitter combines a number of homes (typically less than 100) onto a single, shared optical fibre, which connects to an optical line terminator (OLT) in the telco's CO. The optical splitters have no active electronics and don't require any power to operate.
