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 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. Typically, but not always, there is one input in and multiple outputs. The output signals theoretically possess the following characteristics: Since the 0° power splitter is a reciprocal passive device it. put signal and delivers multiple output signals with specific phase and a power combiner simply by applying each signal singularly into each of the splitter out oss that varies depending upon the phase and amplitude relationship of the signals being combined. Pick the split ratio that matches what you need. Choose the connector type like SC, LC, or FC. This. This is best used for DC and where impedance matching isn't needed since at the junction of the 3 ports, the impedance is ½ the input impedance.
