Comparision Between XFP SFP SFP+ Transceivers
SFP, SFP+, and XFP transceivers all are hot-swappable, which means there's no need to shut down a switch to swap out a module – making it easy to change interfaces for upgrades and maintenance.
SFP transceivers support speeds up to 4.25 Gbps and are generally used for Fast Ethernet or Gigabit Ethernet applications. The expanded SFP standard, SFP+, supports speeds of 10 Gbps and rates up to 16 Gbps. XFP is a separate standard that also supports 10Gbps speeds. The primary difference between SFP+ and the slightly older XFP standard is that the SFP+ moves the chip for clock and data recovery into a line card on the host device. This makes an SFP+ smaller than an 10G XFP, enabling greater port density. The cost of SFP+ is also less than that to the other 10G optical modules XFP, X2 and XENPAK. And it can connect with the same type of XFP, X2 and XENPAK directly.
