In a passive optical network (PON), optical splitters play a crucial role in distributing optical signals to multiple endpoints without the need for powered components. Optical splitters divide the signal that comes from the central office or optical line terminal (OLT) so that it can be shared among multiple subscribers or premises. This functionality allows for an efficient and cost-effective way to serve numerous users through a single optical fiber, which is a fundamental principle of PON technology.

The deployment of optical splitters is what differentiates PON from other types of networks because they enable passive distribution of the optical signal over a point-to-multipoint architecture. This eliminates the need for individual powered amplifiers or signal regeneration along the distribution path, making the network simpler and less expensive to maintain.

The other components mentioned do not serve the same essential function in a PON. For example, while optical amplifiers might enhance signals in other types of fiber networks, they are not necessary in a PON setup since the design relies on passive components. Signal encoders are more related to data formatting and processing, which is not the primary function in the distribution framework of a PON. Coaxial cables are also irrelevant in the context of PON, as PON specifically utilizes
