Active equipment is equipment containing electronic circuits, receiving power from the electrical network or other power sources (batteries, accumulators, solar panels, generator, etc.) and performing the functions of conversion, signal amplification, and others. This means the ability of such equipment to process the signal using special algorithms. In networks, packet data transmission takes place, each data packet also contains technical information: information about its source, purpose, information integrity and others, allowing the packet to be delivered to its destination.Active network equipment not only captures and transmits the signal, but also processes this technical information, redirecting and distributing incoming streams in accordance with the algorithms built into the device's memory. This “smart” feature, along with mains power, is a hallmark of active equipment.
