Optical splitters generally use ratios
Expressed as a ratio or percentage, the splitter ratio indicates the division of optical power among the output ports. For instance, a 1:8 splitter ratio signifies an equal distribution of incoming optical power among eight output ports, with each port receiving 1/8th of the total. 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. Optical splitters, encompassing FBT (Fused Biconical Taper) couplers and PLC (Planar Lightwave Circuit) splitters, are prevalent passive optical devices designed to divide fiber optic light into multiple segments based on a specified ratio.
