SFP+

SFP+ fiber module (10 Gigabit Small Form Factor Pluggable) is a hot-pluggable, protocol-independent optical transceiver that transmits light at 850nm, 1310nm, or 1550nm for 10G BPS SONET/SDH, fiber channel, Gigabit Ethernet, 10 Gigabit Ethernet, and other applications, including DWDM links. XFP includes a digital diagnostic module similar to sff-8472, but has been extended to provide powerful diagnostic tools
