SFP+ Direct Attach Cable
SFP+ stands for "Enhanced Small Form-factor Pluggable" and is an evolution of SFP designed for bitrates around 10 Gb/s. It was first standardized in 2006 as a simple electrical/optical converter but has since gained more advanced functionality and can now handle many of the features supported by XFP, such as CDR and tunable DWDM. SFP+ is a very popular 10G transceiver due to its compact size and is used in networking equipment from several manufacturers. It can be used for protocols such as Ethernet, Fibre Channel, SDH, CPRI, and more. The connector type is LC duplex for the standard two-fiber version and LC simplex for the bidi version.
