Aktiivikaapeleita, also known as active cables, are specialized cables that incorporate electronic components within the cable itself. These components are designed to enhance signal integrity and overcome limitations associated with passive cables, particularly over longer distances or at higher data rates. The active electronics can perform various functions, such as signal amplification, equalization, and re-timing.

The primary benefit of active cables is their ability to compensate for signal degradation, which naturally occurs as signals travel along a cable. Passive cables, especially long ones, can experience attenuation and dispersion, leading to distorted or weak signals at the receiving end. Active cables mitigate these issues by actively processing the signal. This allows for reliable data transmission in applications where passive cables would fail.

Common applications for active cables include high-speed data networking, such as Ethernet and USB, as well as audio-visual systems and specialized industrial or scientific equipment. They are particularly useful for extending the reach of data interfaces beyond the typical limitations of their passive counterparts. For instance, active USB cables can enable connections over much greater distances than standard USB cables. The integrated electronics typically require a small amount of power, which is often supplied through the connected devices or a separate power source. The specific design and functionality of an active cable vary depending on its intended use and the type of signal it carries.
