Small form-factor pluggable plus transceiver (SFP+) direct aach copper (DAC) cables, also known as
Twinax cables, are suitable for in-rack connecons between servers and switches. They are suitable for
short distances, making them ideal for highly cost-eecve networking connecvity within a rack and
between adjacent racks.
NOTE: We recommend that you use only SFP+ DAC cables purchased from Juniper Networks
with your Juniper Networks device.
CAUTION: The Juniper Networks Technical Assistance Center (JTAC) provides
complete support for Juniper-supplied opcal modules and cables. However, JTAC does
not provide support for third-party opcal modules and cables that are not qualied or
