The 10G module has undergone development from 300Pin, XENPAK, X2, and XFP, and finally realized the transmission of 10G signals with the same size as SFP, which is SFP+. With its advantages of miniaturization and low cost, SFP meets the high-density optical module requirements of equipment. Since the standard was implemented in 2002, it has replaced XFP and became the mainstream of the 10G market in 2010.
Advantages of SFP+ optical module:
1. SFP+ has a more compact form factor than X2 and XFP packages (same size as SFP);
2. It can be directly connected with the same type of XFP, X2, XENPAK;
3. The cost is lower than that of XFP, X2 and XENPAK products.
The difference between SFP+ and SFP:
1. The dimensions of SFP and SFP+ are the same;
2. SFP protocol specification: IEEE802.3, SFF-8472;
Differences between SFP+ and XFP:
1. Both SFP+ and XFP are 10G fiber optic modules, and can communicate with other types of 10G modules;
2. SFP+ is smaller in size than XFP;
3. Because of the smaller size SFP+ will signal modulation function, serial/deserializer, MAC, clock and data recovery
(CDR), and Electronic Dispersion Compensation (EDC) functionality moved from the module to the motherboard card;
4. The protocol that XFP complies with: XFP MSA protocol;
5. Protocols compliant with SFP+: IEEE 802.3ae, SFF-8431, SFF-8432;
6. SFP+ is a more mainstream design
