Optical splitters are classified into linear and combined types

There are several types of fiber optic splitters, each with its unique characteristics and applications. A fiber optic splitter is a passive optical component that divides a single incoming optical signal into two or more outgoing signals, or combines multiple incoming signals into one. Its primary role is in Passive Optical Networks (PON), which are the foundation of. A “splitter” is a power splitter. Rarely, there can be two inputs to provide potential redundancy of route. [pdf]
