Cisco Direct Attach Copper (DAC) Cables - Refurbished, Used
Cisco direct attach copper (DAC) cables, also called twinax cables, are copper cable assemblies with integrated pluggable ends that connect switches, servers and storage over short distances. They cost less and draw less power than a pair of optics plus fiber for runs inside a rack or to the next rack. This collection covers 10, 25, 40 and 100 GbE DAC cables and breakout cables. NetworkTigers sells them refurbished, used and new. Every unit is tested before it ships so it works when it arrives.

Which DAC cable do I need?
Match the port type and speed at both ends (SFP+, SFP28, QSFP+ or QSFP28), then the length: the number at the end of the part number is the length in meters, such as SFP-H10GB-CU3M for 3 meters. Passive cables suit short runs; active (ACU) cables reach further. For a breakout cable, check that the port supports breakout mode. Check that your switch or server supports the cable part number, since some platforms check cable coding.
Frequently asked questions
When should I use an AOC instead of a DAC?
Use an active optical cable when the run is longer than a DAC supports or when you want a thinner, lighter cable. Use a DAC for the shortest runs, where it is usually the lowest-cost option.
