SFP+ Direct Attach Copper Cables for EX Series Switches

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 Figure 22 on page 62.
