DAC, also known as Direct Attach Cable, is composed of high-speed cables made of silver-plated copper conductors and foam-insulated core wires. Key characteristics: Media: Copper DAC: shielded twinax conductors (typically 24-30 AWG). The Quad Small Form-factor Pluggable Double Density (QSFP-DD) Interconnect Solution is specifically designed to meet high-density. Among the many decisions, choosing the right interconnect cable - whether Direct Attach Copper (DAC), Active Electrical Cable (AEC), or Active Optical Cable (AOC) is one of the most important. The wrong choice can mean wasted budget, airflow issues, or even performance bottlenecks. This guide walks. Siemon offers a comprehensive line of High-Speed Cable Assemblies, including straight-through/breakout Direct Attach Cables (DAC), Active Copper Cables (ACC), Active Electrical Cables (AEC) and Active Optical Cables (AOC) in speeds up to 800G, in QSFP-DD, OSFP-FT (Finned Top), OSFP-RHS (Riding Heat. The Volex DAC cable product family includes cable assemblies with Small Form-factor Pluggable (SFP), Quad Small Form-factor Pluggable (QSFP), and Octal Small Form-factor Pluggable (OSFP) single and double density modules. Volex offers a comprehensive range of active and passive DAC cables. This article will provide a brief overview of how to choose among the four 400G high-speed cables: DAC, AOC, ACC, and AEC.
