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 41 on page 133.

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 55 on page 133 describes the support for SFP+ passive DAC cable lengths on

EX Series switches for Junos OS releases.
