The Enhanced Small form-factor Pluggable

The enhanced small form-factor pluggable (SFP+) is an enhanced version of the SFP. It supports data rates up to 10 Gbit/s. The SFP+ was first published on May 9, 2006, and version 4.1 published on July 6, 2009.SFP+ supports 8 Gbit/s Fibre Channel, 10 Gigabit Ethernet and Optical Transport Network standard OTU2.

It is a popular industry format supported by many network component vendors.In comparison to earlier XENPAK or XFP modules, SFP+ modules leave more circuitry to be implemented on the host board instead of inside the module.Consideration has to be given to whether the module is linear or limiting. Linear SFP+ modules are appropriate for 10GBASE-LRM otherwise limiting modules are preferred.
