DAC/AOC Cables

Direct attach copper cables (DAC) are twinax copper cables. They directly connect the line cards or ports in active equipment. They are often used to connect switches, data storage devices, routers, or servers in a data network. The module head and the copper cable are merged and inseparable.

DAC cables, especially passive copper cables, are often used for short-distance transmission due to their high transmission speed and affordability.

Active optical cables (AOC) use electrical-to-optical conversion, which results in improved data transfer speed and distance performance. They are compatible with standard electrical interfaces from which they receive electrical signals and use the optical fiber between the connectors to convert them into optical signals.

AOC cables are usually used for devices that require high-speed and high interconnectivity, such as data centers, high-performance computers, and high-capacity memory devices.
