SFP

SFP is short for "small formfactor pluggable" and was standardized in 2001 as replacement for GBIC. Due to this it is also known as a "mini GBIC". As of today, it is the most used type of transceiver covering protocols like Ethernet, SDH, Fibre Channel, OTN, SDI/SMPTE, CPRI and more. Bitrates span from 10Mbit to 10Gbit.
