AOC – Active optical cables
AOC stands for Active Optical Cable. “Active” is this type of cable because they are equipped with transceivers that convert the electrical signals into optical signals. AOC accept the same electrical inputs and outputs as the older copper cables. The only difference here is that the cable ends or connectors fitted with the signal converters are connected by fiber optic cables. The signal converter, in turn, does not require an additional power supply, because it draws its voltage from the bus.
An application example for an AOC cable is crisp 4K playback at 120 hertz and over 30 or more meters, completely lossless. This is possible, for example, with an AOC cable from Delock. Delock active optical cables are designed to transmit HDMI or DisplayPort signals up to 8K resolution or USB or Ethernet signals up to 10 Gbps. Most active optical cables for video are unidirectional and transmit signals up to 100m.
Depending on the application, additional copper lines may be required, e.g. for the power supply in USB or HDMI cables; these are then referred to as hybrid cables. “Hybrid” means that both optical and electrical cores are installed here.
