Active cables are copper cables for data t … Active cables are copper cables for data transmission that use an electronic circuit to boost the performance of the cable. Without an electronic circuit a cable is considered a 'passive' cable. Passive cables are liable to degrade the data they carry, due to "channel impairments" including attenuation, crosstalk and group velocity distortion. In active cables, a circuit using one or several integrated circuits is embedded in the cable to compensate for some or all of these impairments. This active boosting allows cables to be more compact, thinner, longer and transmit data faster than their passive equivalents. Active cables are used in enterprise networks which form the backbone of modern data communication systems, and also to interconnect consumer devices such as cameras, gaming consoles, and HDTVs. Embedding circuitry in cables can allow for less copper to be used in cable production for the same performance, reducing the weight of the cable by as much as 80%, and reduce cable size. Other benefits include longer reach and lower power consumption. longer reach and lower power consumption.
