Use quad small-form factor pluggable plus (QSFP+) direct-attach copper (DAC) cables
to connect a standalone device to other standalone device.
NOTE: The QSFP+ DAC cables consist of a cable assembly terminated with
QSFP+ transceivers on either end.
Table 42 on page 86 describes the Junos OS software releases that supports third-party
DAC breakout cables. Earlier releases do not support third-party breakout cables.
While we highly recommend using Juniper Network DAC cables, you may use cables from
a third-party vendor. 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.
Third-Party DAC Cable Support Added
Junos OS Release 15.1X54-D20
The cables are hot-removable and hot-insertable. A cable consists of a cable assembly
that connects directly into two QSFP+ 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 40 Gbps.
Passive DAC cables have no signal amplification built into the cable assembly.
Table 43 on page 87 describes the passive DAC cable specifications for QSFP+.
Active DAC cables have signal amplification and equalization built into the cable assembly.
Table 44 on page 89 describes the active DAC cable specifications.
