Direct Attach Cables are pre-terminated high-speed twinax copper cables with integrated transceivers. Unlike discrete transceivers plus patch cords, DACs consume near-zero power and generate almost no heat, making them ideal for short-range (1–5 m) in-rack links. 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. Unlock 100G performance with BizLink's DAC cables. These cables can be employed in high-end data centers. Utilizing differential signal transmission technology, DACs provide a cost-effective, "zero-latency" alternative to optical transceivers for. DAC cables provide short-range, high-speed connectivity using copper cables. Passive DACs have minimal electronics and therefore draw very low power (typically less than 0.
