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. In modern FTTH (Fiber to the Home) and optical communication networks, three types of fiber distribution products are widely used: Splitter Distribution Box, ODF (Optical Distribution Frame), and Fiber Terminal Box. This article explores how optical splitters are applied in PON networks, comparing centralized and cascaded architectures, their advantages, and real-world. Each device is engineered for a specific role in the fiber optic network, from the central hub to the end user. A Splitter Distribution Box, commonly referred to as FDB, is a specialized fiber management box designed primarily for optical signal splitting and distribution.
