In fiber optic networks, particularly in FTTx (Fiber to the x) and PON (Passive Optical Networks) deployments, splitters play a central role in distributing the optical signal from a single source to multiple destinations. These are known as passive optical splitters, and they perform the function. The formula for the theoretical loss for each output port of a splitter with N output ports is: Theoretical Split Loss (in dB) = 10 * log10 (N) Where: N is the number of output ports the splitter has (e., 2 for a 1x2 splitter, 4 for a 1x4, 8 for a 1x8, 32 for a 1x32, etc. Passive split links usually lose the most dB at the splitter, so we keep the optical budget and the installed route separate.
