  Spartanburg SC | GoUpstate.com | Spartanburg Herald-Journal
It interfaces a network device mother board (for a switch, router or similar device) to a fiber optic or unshielded twisted pair networking cable.
SFP transceivers are also available with a "copper" cable interface, allowing a host device designed primarily for optical fiber communications to also communicate over unshielded twisted pair networking cable.
The SFP was designed after the GBIC interface, and allows greater port density (number of transceivers per inch along the edge of a mother board) than the GBIC, which is why SFP is also known as mini-GBIC.

The SFP standard evolved from the Gigabit Interface Converter (GBIC) modules that were standardized as a part of Gigabit Ethernet.
Using SFP transceivers, it is possible to create a universal media management device that goes well beyond the capabilities and limitations of the traditional media converter.
The SFP standard is fueling today’s advancements in next-generation fiber grooming to allow telecom engineers the ability to seamlessly blend existing multimode fiber, copper, or single mode fiber.

 Lightwave - Optical Ethernet bridges the gap from provider to customer
SFP interfaces: Small form-factor pluggable (SFP) interfaces are a new style of optical physical layer interface that can be swapped out to allow changes to be made to the network type.
With SFP interfaces, more expenses are avoided by making it possible for the network to accommodate a wide range of applications with a relatively small number of components.
For example, if a link is lost on the fiber trunk between the CO and CPE, the OES demarcation units at each end automatically disable all their interfaces.
