Small form-factor pluggable plus transceiver (SFP+) direct attach copper 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 7 m (23 ft), making them ideal
for highly cost-effective networking connectivity within a rack and between adjacent
racks. See Figure 39 on page
