SFP+ optical modules advantages

7/3/15  |  Technical Article

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

SFP+ optical module advantages
1. SFP+ is more compact than the X2 and XFP packages (same size and SFP);
2. Can be the same type of XFP, X2, XENPAK direct connection;
3. Cost ratio XFP, X2, XENPAK low;
4. SFP+ smaller, the signal modulation function, serial / deserializer, MAC, clock and data recovery (CDR), as well as electronic dispersion compensation (EDC) function from the module over the board cards.

SFP+ and XFP, SFP difference
1. SFP+ is smaller than the XFP form factor;
2. XFP protocol specification: XFP MSA agreement;
3. SFP protocol specification: IEEE802.3, SFF-8472;
4. SFP+ protocol specification: IEEE 802.3ae, SFF-8431, SFF-8432;
