Optical Interface Support in EX3200 and EX4200 Switches
Optional uplink modules for EX3200 and EX4200 switches support SFP, SFP+, or XFP
transceivers. This topic describes the optical interfaces supported for those transceivers.
It also lists the copper interface supported for the SFP transceivers.
NOTE: Use only optical transceivers and optical connectors purchased from Juniper
Networks for your EX Series switch.
The Gigabit Ethernet SFP, SFP+, or XFP transceivers installed in EX3200 or EX4200
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. The command does not give any output for copper transceivers, Fast
Ethernet transceivers, or transceivers not purchased from Juniper Networks.
The tables in this topic describe the optical interface support over single-mode fiber-optic
(SMF) and multimode fiber-optic (MMF) cables for SFP, SFP+, and XFP transceivers
and over the copper interface for SFP transceivers:

Ethernet SFP transceivers.
