Many people do not know the difference between sfp and sfp+, so sometimes it brings unnecessary trouble. 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 to become 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 its smaller size, SFP+ moves signal modulation, serial/deserializer, MAC, clock and data recovery (CDR), and electronic dispersion compensation (EDC) functions 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.

3. SFP+ protocol specification: IEEE 802.3ae, SFF-8431, SFF-8432.
