Small form-factor pluggable plus (SFP+) direct attach copper (DAC) cables, also known
as Twinax cables, are suitable for in-rack connections between servers.
While we highly recommend using Juniper Network DAC cables, ACX5000 routers 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 are having a problem running a Juniper Networks device
that is using 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 36 on page 77 describes the Junos OS software releases that supports third-party
DAC cables. Prior releases only permitted Juniper Networks DAC cables.
The cables are hot-removable and hot-insertable. A cable consists of a cable assembly
that connects directly into two SFP+ modules, one at each end of the cable. The cables
use integrated duplex serial data links for bidirectional communication and are designed
for data rates up to 10 Gbps. There are two types of DAC cables:
Passive DAC cables have no signal amplification built into the cable assembly.
Table 37 on page 78 describes the passive DAC cable specifications.
Active DAC cables have signal amplification and equalization built into the cable
assembly. Table 38 on page 80
