For a list of the SFP modules that the switches support, see the Catalyst 3750 release notes.

SFP Modules

The Catalyst 3750 switch uses Gigabit Ethernet SFP modules to establish connections to other devices.
These transceiver modules are field-replaceable, providing the uplink interfaces when inserted in an SFP
module slot. You can use the SFP modules for Gigabit uplink connections to other switches. You use
fiber-optic cables with LC or MT-RJ connectors to connect to a fiber-optic SFP module. You use
Category 5 cable with RJ-45 connectors to connect to a copper SFP module.
For more information about these SFP modules, see your SFP module documentation.

XENPAK Module Slot

The Catalyst 3750G-16TD switch uses 10-Gigabit Ethernet XENPAK modules to establish connections
to networks. The modules are installed in the module slot in the switch front panel.
