Pluggable Transceivers Supported on EX4300 Switches
You can nd the list of transceivers supported on EX4300 switches except EX4300-48MP and
EX4300-48MP-S switches and informaon about those transceivers at the Hardware Compability Tool
page for EX4300.
You can nd the list of transceivers supported on EX4300-48MP and EX4300-48MP-S switches and
informaon about those transceivers at the Hardware Compability Tool page for EX4300 Mulgigabit.
NOTE: We recommend that you use only opcal transceivers and opcal connectors 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
supplied by Juniper Networks. If you face a problem running a Juniper device that uses
third-party opcal modules or cables, JTAC may help you diagnose host-related issues if
the observed issue is not, in the opinion of JTAC, related to the use of the third-party
opcal modules or cables. Your JTAC engineer will likely request that you check the
third-party opcal module or cable and, if required, replace it with an equivalent
Juniper-qualied component.
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 transceivers installed in EX4300 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.
