Differences between SFP and SFP +

Edit: Shaoxing ZKTel Equipment Co.,Ltd    Date: May 20, 2017

Many people do not know the difference between sfp and sfp +, so sometimes bring unnecessary trouble. 10G module has experienced from the 300Pin, XENPAK, X2, XFP development, and ultimately achieved the same size and SFP transmission 10G signal, which is SFP +. SFP with its small and low cost and other advantages to meet the equipment on the optical module high-density needs, from the 2002 standard implementation, to 2010 has replaced XFP to become the mainstream market 10G.


SFP + optical module advantages:

1, SFP + has a more compact form factor (same size as SFP) than X2 and XFP packages;

2, and the same type of XFP, X2, XENPAK direct connection;

3, the cost is lower than XFP, X2, XENPAK products.


Differences between SFP + and SFP:

1, SFP and SFP + appearance of the same size;

2, SFP protocol specification: IEEE802.3, SFF-8472;

Differences between SFP + and XFP:

1, SFP + and XFP are 10G fiber modules, and with other types of 10G modules can be interoperable;

2, SFP + smaller than the XFP size;

3, because the smaller size of the SFP + signal modulation function, serial / deserializer, MAC, clock and data recovery (CDR), and electronic dispersion compensation (EDC) function from the module to the motherboard;

4, XFP compliance protocol: XFP MSA protocol;

5, SFP + compliant protocols: IEEE 802.3ae, SFF-8431, SFF-8432;

6, SFP + is more mainstream design.

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