You can use DAC cables purchased from a third party. These cables should meet the
specifications described in
Table 36 on page 119 and Table 37 on page 122 . Table 35 on
page 118 describes the Junos OS software releases that supports third-party DAC cables.
Prior releases do not support third-party DAC cables.
Table 35: Third-Party DAC Cable Support
Third-Party Cable Supported Platform
Junos OS Release 11.3R1 or later QFX3000 QFabric system
Junos OS Release 11.3R4 or later QFX3500 device as a standalone switch
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
36 on page 119 describes the passive DAC cable specifications.
• Active DAC cables have signal amplification and equalization built into the cable
assembly.
Table 37 on page 122 describes the active DAC cable specifications.
