What Is SFP+?
SFP+, also called SFP Plus, is short for enhanced small form-factor pluggable. As its name suggests, SFP+ is an enhanced version of the SFP that supports data rates up to 16 Gbit/s. SFP+ is with more compact size compared with the former 10G transceivers X2 and Xenpak, it has greater ability for density installations.
SFP+ Transceiver is interchangeable with SFP transceiver and can be used in the same cages as SFP transceiver. For 10G applications, SFP+ transceiver has a smaller footprint and lower power consumption than XFP transceiver. The electrical interface to the host board for SFP transceiver and SFP+ transceiver is the same serial.

The SFP+ specification 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.
Although the SFP+ standard does not include mention of 16G Fibre Channel it can be used at this speed. Besides the data rate, the big difference between 8G Fibre Channel and 16G Fibre Channel is the encoding method. 64b/66b encoding used for 16G is a more efficient encoding mechanism than 8b/10b used for 8G, and allows for the data rate to double without doubling the line rate. The result is the 14.025 Gbit/s line rate for 16G Fibre Channel.
Comparisons With SFP and XFP
SFP+ and SFP have the same size and appearance, what makes them different is that SFP is based on IEEE802.3 and SFF-8472, however, SFP+ is compliance with the protocol of IEEE802.3ae, SFF-8431, SFF-8432. What’s more, their transmission rates are also different: SFP+ is 10 Gbps, while SFP is usually 1.25G, 155M, 2.5G and other rate.
In comparison to earlier XFP modules, SFP+ modules leave more circuitry to be implemented on the host board instead of inside the module. The primary difference between SFP+ and the slightly older XFP standard is that SFP+ moves the chip for clock and data recovery into a line card on the host device. This makes the SFP+ smaller than an XFP, enabling greater port density. XFP is based on the standard of XFP MSA, while SFP+ is compliance with the protocol of IEEE802.3ae, SFF-8431 and SFF-8432.
