This involves having 2 or more splitter combinations to arrive at the target split ratio. A classic example is the use of a 1x4 and 1x8 splitter to comprise a 1x32 final ratio.

In this one-to-many topology, a single fiber serving many sites branches into multiple fibers through a passive splitter, and those fibers can each serve multiple sites through further splitters.

An optical splitter takes light from one fiber and splits it into two or more light streams. They are used in FTTH systems if you decide to go with a GPON architecture (see the Optical Line Terminal page for
