Small form-factor pluggable plus (SFP+) direct attach copper (DAC) cables, also known
as Twinax cables, are suitable for in-rack connections between servers and either the
QFX5100-48S, QFX5100-96S, or QFX3500 devices. Juniper Networks SFP+ DAC cables
may also be used in QFX Virtual Chassis and Virtual Chassis Fabric (VCF).
While we highly recommend using Juniper Network DAC cables, QFX Series switches do
support third-party DAC cables. If you choose to use a third-party cable, it should meet
the specifications described in
CAUTION: If you face a problem running a Juniper Networks device that uses
a third-party optic or cable, the Juniper Networks Technical Assistance Center
(JTAC) can help you diagnose the source of the problem. Your JTAC engineer
might recommend that you check the third-party optic or cable and potentially
replace it with an equivalent Juniper Networks optic or cable that is qualified
for the device.
Table 40 on page 126 describes the Junos OS software releases that supports third-party
DAC cables. Prior releases only permitted Juniper Networks DAC cables.
NOTE: This topic does not describe which devices support these transceivers.
