The Cisco 100BASE-X Small Form-factor Pluggable (SFP) is a hot-swappable input/output device that plugs into a Fast Ethernet port or slot, linking the port with the network.
Main features include the following:
Hot-swappable when deployed, the switch or router does not have to reboot.
Supports the "pay-as-you-populate" model.
Interchangeable with other 100BASE-X SFPs on the same line card.
Supports the Cisco quality ID feature that enables the switch or router to identify whether or not the SFP is a Cisco qualified SFP.
Optically interoperable with respective 100BASE-X Ethernet interfaces on the same link.

Technical Specifications
Platform Support
The Cisco SFPs are supported across a variety of Cisco Systems switches, routers, and optical transport devices. For more details, refer to the document Cisco 100M Ethernet SFP Compatibility Matrix.
Connectors and Cabling
Connectors: Dual LC connector (GLC-FE-100FX, GLC-FE-100FX-RGD, GLC-FE-100LX, GLC-FE-100LX-RGD, GLC-FE-100EX and GLC-FE-100ZX) or single LC connector (GLC-FE-100BX-D and GLC-FE-100BX-U)
Table 1 provides cabling specifications for the SFPs for installation in a Fast Ethernet SFP port. Note that all SFP ports have LC-type connectors, and the minimum cable distance for all SFPs listed (MMF and SMF [G.652] is 2 meters [6.5 feet]).
