Juniper EX4300 Hardware Guide

NOTE: The transceivers support DOM even if they are installed in the SFP+
uplink module ports or QSFP+ ports configured as Virtual Chassis ports
(VCPs).
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 QSFP+ transceivers
and the copper interfaces supported for the SFP transceivers:
•
Table 69 on page 111—Optical interface support and copper interface support for
Gigabit Ethernet SFP transceivers.
•
Table 70 on page 120—Optical interface support for Fast Ethernet SFP transceivers.
NOTE: Only the SFP network ports on 32-port EX4300 switches support
Fast Ethernet SFP transceivers. The built-in uplink ports or the uplink
module ports do not support Fast Ethernet SFP transceivers.
