Small form-factor pluggable plus transceiver (SFP+) direct attach copper (DAC) cables,
also known as Twinax cables, are suitable for in-rack connections between servers and
switches. They are suitable for short distances, making them ideal for highly cost-effective
networking connectivity within a rack and between adjacent racks. See
