Fold difference between SFP and SFP +
1, SFP, and SFP + sizes look the same;
2, SFP protocol specification IEEE802.3, SFF-8472;
Difference between folding SFP+ and XFP
1, XFP and SFP + optical fiber module are 10G, and 10G modules with other types of coverage;
2, SFP+ a smaller size than the XFP appearance;
3, because of its smaller size SFP+ signal modulation capabilities, serial/deserializer, MAC, clock and data recovery (CDR), as well as electronic
Dispersion compensation (EDC) function from the module to the motherboard on the card;
4, XFP compliance agreement: XFP MSA agreements;
5, SFP+ to comply with the Protocol: IEEE 802.3AE, SFF-8431, SFF-8432;
6, SFP+ is a more mainstream design.
7, SFP+ Protocol: IEEE 802.3AE, SFF-8431, SFF-8432.
Advantage folding SFP + optical modules
1, SFP+ is better than X2 and XFP package more compact overall dimensions (same size and SFP);
2, and XFP,X2,XENPAK of the same type can be connected directly;
3, cost is lower than XFP,X2,XENPAK.
SFP jumper categories: LC, SC, FC, TC.
