SFP Definition
SFP specifications are based on IEEE802.3 and SFF-8472 with the max speed of 4.25 Gbps. The SFP stands for Small Form-factor Pluggable. It is a hot-pluggable transceiver that plugs into the SFP port of a network switch and commonly supports Gigabit Ethernet, and Fibre Channel either in the multimode or sing-mode fibers.
SFP+ Definition
The SFP+ supports data rates up to 16 Gbps and it is an enhanced version of the SFP which is based on SFF-8431. SFP+ is commonly found in 10Gbit Ethernet or 8/16 Gbit FibreChannel technologies.
