A splitter is a device that divides the power of a single input signal into multiple equal outputs. It typically has one input port and several output ports. These devices are commonly categorized based on the number of output channels, such as two-way, three-way, four-way, or six-way splitters. However, there are various other classification methods depending on their application environment, construction type, and technical design. Splitters can be divided into indoor and outdoor (waterproof) types, depending on where they are used. They may also differ in terms of installation style—such as feed-through or standard types, surface-mounted or recessed models—and in materials, like common plastic enclosures or metal-shielded cases. Additionally, they can be classified as either lumped parameter or distributed parameter types. The lumped parameter type includes resistance-based and magnetic core coupling transformer designs, while the distributed parameter type often uses microstrip line technology.

In contrast, a brancher serves a different purpose by taking a portion of the signal from the main transmission line and directing it to a user terminal. It usually has a main output and several branch outputs. Like splitters, branchers are also categorized based on the number of branch ports. They too can be classified as lumped parameter or distributed parameter types, but their function and design are distinct from those of splitters. One key difference between a splitter and a brancher lies in how they distribute energy. A splitter evenly distributes the input power across all its output ports, with no distinction between primary and secondary outputs. On the other hand, a brancher maintains a clear hierarchy: the main output carries most of the signal power, while the branch outputs receive only a small portion. This fundamental difference affects their functionality, application scenarios, circuit design, and technical specifications, making them suitable for different use cases in communication and signal distribution systems.
