Optical splitters are classified based on their package style, transmission medium, and manufacturing technique. 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. This guide. A “splitter” is a power splitter. A splitter is not a filter like a wavelength division multiplexer (WDM). Rarely, there can be two inputs to provide potential redundancy of route. Light power goes in and light power coming out. A fiber-optic splitter, also known as a beam splitter, is based on a quartz substrate of an integrated waveguide optical power distribution device, similar to a coaxial cable transmission system.
