The Difference Between SFP+ And SFP、XFP
June 20,2016 16:10:34

In order to make the people learn the difference between SFP+ and SFP、XFP, and avoid unnecessary trouble to the customer, so we share some information for them .

10G optical module has experienced the development from 300Pin, XENPAK, X2, XFP, finally realize the transmission of 10G signal with the same size as SFP, this is SFP+. SFP+ meets the requirements of the equipment to optical module high-density, has gradually replaced XFP and become the mainstream of 10G market.

SFP package---Hot plug small package module, the highest rate is up to 4G, usually connect LC interface.
SFP+ package---Standard package, the work rate is 10G, can meet the application of Ethernet 10G.
XFP package---A standardized package of serial 10G optical transceiver modules.

The advantages of SFP+ optical module
1、SFP+ has a more compact outline size than the X2 and XFP packages (same as SFP);
2、It has directly connected with the same type of XFP, X2, and XENPAK;
3、Cost is lower than XFP, X2, XENPAK

The difference between SFP and SFP+: 
1、The appearance and the size of SFP and SFP+ are the same;
2、The highest rate of SFP is up to 4G,the rate of SFP+ is 10G;
3、The protocol specification of SFP:SFP:IEEE802.3、SFF-8472 ;   
4、SFP+ supports DDM. 

The difference between SFP+ and XFP:  
1、SFP + and XFP both are 10G optical module, and can be connected with other types of 10G modules; 
2、The appearance and the size of SFP+ is smaller than XFP;
3、Because of the smaller size, SFP+ moves the signal modulation function, Serial / deserializer, MAC, clock and data recovery (CDR), and electronic dispersion compensation (EDC) function to the main board card from modules; 
4、Compliance Agreement of XFP: XFP MSA agreement; 
5、Compliance Agreement of SFP+: IEEE 802.3ae、SFF-8431、SFF-8432; 
6、SFP+ is a more mainstream design;
7、The protocol specification of SFP+:IEEE 802.3ae、SFF-8431、SFF-8432。
Although they have some differences,our module can be compatible with Cisco, Avago, Extreme, HUAWEI, H3C, ZTC, Avago,Extreme,Zyxel, Juniper,  Alcatel, D-Link, HP switch etc.
