Direct Attach Copper (DACs) cables are most often used over short distances, connecting units in the same server rack. They can be active or passive – active connections are part of signal processing circuitry, and passive connections simply carry power. In the case of a DAC, the cable is made of copper rather than fiber.

Blog Post: The Data Link Layer – How DAC and AOC Cables Can Work For You
As the need for data storage and speed increases, the need for hyperscale data centers has increased. So has the need for edge data centers as well. While large-scale centers serve companies like Amazon, Microsoft, and Google, other organizations are looking at smaller data centers closer to the end-user. In both cases, the data link layer of the data center is critical. Enter Direct Attach Copper (DACs) cables and Active Optical Cables (AOCs).
