Juniper EX4100

Use of third-party opcal modules with high-power consumpon (for example,
coherent ZR or ZR+) can potenally cause thermal damage to or reduce the lifespan of
the host equipment. Any damage to the host equipment due to the use of third-party
opcal modules or cables is the users’ responsibility. Juniper Networks will accept no
liability for any damage caused due to such use.
The Gigabit Ethernet (GbE) transceivers installed in EX4100 and EX4100-F switches support digital
opcal monitoring (DOM). You can view the diagnosc details for these transceivers by issuing the
operaonal mode CLI command show interfaces diagnostics optics .
NOTE: The transceivers support DOM even if you install the transceivers in ports that you
congured as Virtual Chassis ports (VCPs).

Standards Supported by These Cables | 104
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
