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 of up to 23 ft (7 m), making them ideal
for highly cost-effective networking connectivity within a rack and between adjacent
racks. See
