Lowering the first-stage beam splitter reduces construction costs
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 contrast, FBT splitters are produced through fused biconical tapering, offering lower cost at small split ratios but with less stability in wide-temperature environments and limited scalability. In summary, FBT splitters are suitable for cost-sensitive, small-scale applications, while PLC. 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.
