What’s the difference among the Cisco XFP and SFP+?
SFP+ and XFP, all refer to a type of transceiver that is plugged into a special port on a switch or to some network device. These transceivers are used in the field of telecommunication and data communication.
SFP+ can be referred to as an expansion of the SFP standard. SFP+ modules are smaller than XFP. It has the capability to support speeds of 10 Gbps or even higher over fiber. The SFP+ product family includes cages, connectors, and copper cable assemblies. It is also similar to the performance requirements of SFF-8431 and also supports 8G Fiber Channel and 10G Ethernet applications. SFP+ comes with various advantages. It is a more compact factor package than compared to that of XFP. The cost of SFP+ is also less than that to the XFP, X2 and XENPAK. And it can connect with the same type of XFP, X2 and XENPAK directly.
XFP (10 Gigabit Small Form Factor Pluggable) is a standard for the transceivers. This type of transceiver is not dependent on the protocol. Generally, it operates at optical wavelenghts corresponding to 850nm, 1310nm or 1550nm. The modules belonging to the XFP are hot swappable which means that the function of replacing the computer system components can be performed without shutting down the system. The specifications of XPF were developed by the XFP Multi Source Agreement Group. XFP complies with the agreement known as XFP MSA agreement.
What’s the connection between XFP and SFP+? Both of them are 10G fiber optical modules and can connect with other type of 10G modules. The size of SFP+ is smaller than XFP, thus it moves some functions to motherboard, including signal modulation function, MAC, CDR and EDC. XFP is based on the standard of XFP MSA. SFP+ is compliance with the protocol of IEEE802.3ae, SFF-8431, SFF-8432. SFP+ is the mainstream design.
Both XFP module and SFP+ module are 10G fiber optical modules and they are mainly used in 10G fiber optic networking. However, there are still some differences between them.
XFP is based on the standard of XFP MSA, while SFP+ is an enhanced version of the SFP and is based on the SFP+ MSA. XFP is compliant to 10 Gbit/s Fibre Channel, but SFP+ supports 8 Gbit/s Fibre Channel.The size of XFP is larger than SFP+, so their packages are different.
In comparison to XFP, SFP+ leaves more circuitry to be implemented on the motherboard instead of inside the module because it moves some functions to motherboard, including signal modulation function, MAC, CDR and EDC.
For 10G cable, SFP+ introduces Direct Attach Cable (DAC) for connecting two SFP+ ports without dedicated transceivers, but XFP has no cable version.
An SFP+ port can accept 16G SFP+ transceiver. If the switch accepts 1G and 10G optics in the SFP+ port, then you can put in SFP module to suit your needs. While XFP ports only accept XFP transceivers.
