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, making them ideal for highly cost-effective
networking connectivity within a rack and between adjacent racks. See
Figure 23 on page 81.

Cable Specifications
EX Series switches support SFP+ passive DAC cables. The passive Twinax cable is a
straight cable with no active electronic components. EX Series switches support 1 m,
3 m, 5 m, and 7 m long SFP+ passive DAC cables. For the full specifications of these
cables, see The Hardware Compatibility Tool.
Table 40 on page 81 describes the support for SFP+ passive DAC cable lengths on
EX Series switches for Junos OS releases.
