Sfp+ Direct Attach Copper Cables For Ex Series Switches - Juniper EX4100 Hardware Manual

Use of third-party optical modules with high-power consumption (for example,
coherent ZR or ZR+) can potentially 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
optical 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
optical monitoring (DOM). You can view the diagnostic details for these transceivers by issuing the
operational mode CLI command
NOTE: The transceivers support DOM even if you install the transceivers in ports that you
configured as Virtual Chassis ports (VCPs).

Standards Supported by These Cables | 104
Small form-factor pluggable plus transceiver (SFP+) direct attach copper (DAC) cables, also known as
Twinax cables, are suitable for in-rack connections between servers and switches. They are suitable for
short distances, making them ideal for highly cost-effective networking connectivity 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 optical modules and cables. However, JTAC does
show interfaces diagnostics optics
