Optical Interface Support in EX4500 Switches
Uplink module ports on EX4500 switches support SFP and SFP+ 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 EX4500 switch. |
The Gigabit Ethernet SFP and SFP+ transceivers installed in EX4500 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 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 and SFP+ transceivers and over the copper interface for SFP transceivers:
- Table 1—Optical interface support and copper interface support for Gigabit Ethernet SFP transceivers.
- Table 2—Optical interface support for Gigabit Ethernet SFP+ transceivers.
