Optical Interface Support—EX 3200 and EX 4200 Switches
Optional uplink modules for EX 3200 and EX 4200 switches support either 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.
Table 12 on page 21 describes the optical interface support over single-mode
fiber-optic (SMF) and multimode fiber-optic (MMF) cables for SFP transceivers in
EX 3200 and EX 4200 switches.
