Since SFP only supports the transmission rate of 4.25 Gbps, which cannot meet people's requirements for higher and higher network speed, SFP+ was born in such a background.
The SFP+ has a maximum transmission rate of 16 Gbps. In fact, the SFP+ is an enhanced version of the SFP. The SFP+ specification is based on sof-8431. In most applications today, the SFP+ module typically supports 8 Gbit/s fibre channel.
By virtue of its small size and convenient use, SFP+ module has replaced XENPAK and XFP modules, which were widely used in early 10 gigabit Ethernet, and become the most popular optical module in 10 gigabit Ethernet.
