Pluggable Transceivers Supported on EX4300 Switches
Optional uplink modules for EX4300 switches support SFP, SFP+, and QSFP+
transceivers. This topic describes the optical interfaces supported for those transceivers.
It also lists the copper interfaces supported for the SFP transceivers.
NOTE: We recommend that you use only optical transceivers and optical
connectors purchased from Juniper Networks with your Juniper Networks
device.
CAUTION: If you face a problem running a Juniper Networks device that uses
a third-partyoptic or cable, the Juniper Networks Technical AssistanceCenter
(JTAC) can help you diagnose the source of the problem. Your JTAC engineer
might recommend that youcheck the third-partyoptic or cableand potentially
replace it with an equivalent Juniper Networks optic or cable that is qualified
for the device.
The Gigabit Ethernet SFP, SFP+, and QSFP+ transceivers installed in EX4300 switches
support digital optical monitoring (DOM): You can view the diagnostic details for these
transceivers by issuing the operational mode CLI command show interfaces diagnostics
optics.
