Difference between SFP, SFP+, QSFP, QSFP+, XFP and CFP Modules

SFP:

--> SFP stands for Small Form Factor Pluggable and it is also called as mini GBIC.

--> SFP transceiver modules support SONET, Fast Ethernet, Gigabit Ethernet, Fibre Channel, and other communications standards.

--> Copper cables and fiber cables can be used in SFP module.

--> SFP supports data rate up to 5 Gbps.



SFP+

--> SFP+ stands for small form factor pluggable plus.

-->  SFP+ transceiver modules support Gigabit Ethernet, Fibre Channel, and other communications standards.

--> Twinax cables, Copper Cables and fiber cables can be used in SFP+ module.

--> SFP+ supports data rate upto 10 Gbps.



QSFP and QSFP+

--> QSFP stands for Quad Small Form-factor Pluggable.

--> The QSFP transceiver module supports Ethernet, Fibre Channel, InfiniBand and SONET/SDH standards with different data rate options.

--> Quad-SFP (QSFP) ports use a single MTP connector supports up to four channels or ports. 

-->  QSFP+ stands for Quad Small Form-factor pluggable plus. The difference is only the data rate between the QSFP and QSFP+ 

--> QSFP has four-channel SFP interfaces which can transfer rates up to 4x1Gbps.

--> QSFP+ has four-channel SFP+ interfaces which can transfer rates up to 4x10Gbps.

--> QSFP28 is a four-channel QSFP+ module to carry 100 Gbps Ethernet.



XFP:

--> XFP stands for 10 Gigabit Small Form Factor Pluggable.

--> XFP transceiver modules support SONET, 10 Gigabit Ethernet, 10 Gigabit Fibre Channel, and other communications standards.

--> XFP is a slightly larger form factor than the popular small form-factor pluggable transceiver, SFP, and SFP+.

--> XFP modules are hot-swappable and protocol-independent. 

--> XFP supports data rate up to 10 Gbps.



CFP:

--> CFP stands for C form-factor pluggable.

--> The CFP is a multi-source agreement to produce a common form-factor for the transmission of high-speed digital signals.

--> CFP standard was primarily developed for 100 Gigabit Ethernet systems.

--> CFP supports data rate upto 100 Gbps.
