DAC Cable

The undisputed price-performance champions in the server rack: DAC Cables (Direct Attach Copper) are the smartest solution when you want to connect devices over extremely short distances (usually 1 to 3 meters). Instead of buying expensive fiber optic cables and two separate optical transceiver modules, a DAC cable, often called a Twinax cable, gives you an all-in-one package! The transceivers are already permanently attached to the ends of the copper cable. Just plug it in and instantly establish a blazing-fast uplink connection!


Why networking pros rely on Direct Attach Copper:

  • Unbeatable Cost Efficiency: Since the SFP/QSFP modules are already integrated, you save massively on hardware costs compared to optical connections.
  • Plug & Play Perfection: Whether switch-to-switch, router-to-switch, or NAS-to-server – DAC cables are ready to use immediately and do not require complicated cleaning like fiber optics.
  • Low Power Consumption & Latency: Without the need for optical-electrical conversion, these cables consume extremely little power and offer the lowest possible latency.
  • For Every Speed: Our range covers everything – from classic 10G (SFP+) connections and 25G (SFP28) to massive 40G (QSFP+) and 100G (QSFP28) uplinks.

Find the right DAC cable in your required length now and connect your high-end hardware without any bottlenecks!
