The differences between SFP and SFP+

1、SFP doesn‘t support 10G transmission data rate that means they can‘t be used in the same network.

2、From the price, SFP+ is a little bit more expensive than SFP.

The Connection between XFP and SFP+

1、Both of them are 10G fiber optical modules and can connect with other type of 10G modules.

2、The size of SFP+ is smaller than XFP, thus it moves some functions to motherboard, including signal modulation function, MAC, CDR and EDC.

3、XFP is based on the standard of XFP MSA

4、 SFP+ is the mainstream design.

The Advantages of SFP+ Module      

1、SFP+ has a more compact form factor package than X2 and XFP.

2、It can connect with the same type of XFP, X2 and XENPAK directly.

3、The cost of SFP+ is lower than XFP, X2 and XENPAK.

Development of 10G Module 

The 10G module has been developed from 300Pin. XENPAK, X2, XFP and finally achieve with the same size as SFP which can transmit 10G signals called SFP+.
