Haaroittajat

Haaroittajat, commonly known as splitters in English, are passive electronic components used in signal processing and telecommunications. Their primary function is to divide an input signal into two or more output signals. These output signals typically have a reduced amplitude compared to the original input signal. The division of power is usually fixed and depends on the design of the splitter.

There are various types of haaroittajat, differing in their construction and application. In coaxial cable systems, simple T-connectors can act as basic splitters, but they often introduce signal loss and impedance mismatches. More sophisticated splitters, like those used in cable television or satellite dish installations, are designed to minimize signal degradation. They are often housed in metal casings to provide shielding and maintain signal integrity.

The most common type is the 2-way splitter, which divides a signal into two. However, splitters with 4, 6, 8, or even more output ports are also available. The insertion loss, a measure of how much the signal power is reduced by the splitter, is a critical parameter. Higher insertion loss means a weaker signal at the output. Impedance matching is also crucial to prevent signal reflections and maximize power transfer. Haaroittajat are essential in scenarios where a single signal source needs to be distributed to multiple receivers or devices without the need for amplification at each output. They are widely used in residential cable TV setups, broadband internet distribution, and professional audio-visual systems.
