The SFP is the abbreviation for the small FORM pluggable and can be easily understood as an upgraded version of the Gbic. The SFP module is half the size of the Gbic module, and can be configured with more than one port number on the same panel. The other features of the SFP module are basic and gbic consistent. Some switch vendors call the SFP module a miniaturized GBIC (mini-gbic). The SFP module is half the size of the Gbic module, and can be configured with more than one port number on the same panel. The SFP module has the same basic functionality as the gbic.

Adapted to optical fiber home (FTTH) requirements, miniaturization (SAMLL Form FACTOR;SFF) optical signal Receiver (transceivers) demand. SFF and PCB are combined with pin-foot welding needs. To make it easier to use on PCs, there were 1 volumes that were close to SFF long ago, but with an SFP (Small Form PLUGGABLE;SFP) that does not require a pin to be welded between the boards. In addition to this, there is a slightly larger size, with the circuit board in the side contact, also do not need to weld the GBIC specifications, it is another product. ---http://bianceng.cn (computer science)
