Difference Between SFP And SFP+

Difference between SFP and SFP+ Today there are different optical transceivers available on the market. They come in various form factors offering speeds from 100Mbps to 100Gbps and are fully compliant to the MSA and IEEE 802.3 standards. Some of the more popular form factors include SFP, SFP+, XFP, GBIC, XENPAK, QSFP and QSFP28.

SFP SFP in short means Small Form-factor Pluggable. It is a compact and hot-pluggable transceiver that can be used in the ports of telecommunication and data communication devices. It is an industry standard which is manufactured by many network component vendors. SFP modules are designed to support SONET, Gigabit Ethernet, Fibre Channel and other communication standards. Owing to its small size and enhanced capability combined with greater speeds it has made the universally used GBIC (Gigabit Interface Converted) obsolete and hence is sometimes referred to as Mini-GBIC.

SFP+ SFP+ stands for Small Form-factor Pluggable Plus – SFP+ transceivers are an enhanced version of the SFP that can support data rates of up to 16Gbps. The SFP+ specification was first published on May 9th 2006 and the first version 4.2 was published on July 6th 2009. As one of the most popular industry standards it is supported by many network component vendors. SFP+ supports 8 Gbit/s Fibre Channel, 10 Gigabit Ethernet and the Optical Transport Network standard OTU2.
