SFP is a new generation of Wan modules that can meet the 8.5G and Ethernet 10G applications in accordance with the ANSI T11 protocol. The SFP is about 30% smaller than the size of the early XFP light module, and is the same as the normal 1-4g SFP light module appearance. SFP retains only the basic electro-optic, Video SFP photoelectric conversion function, reducing the original XFP design of the SerDes, CDR, EDC, Mac and other signal control functions, thus simplifying the 10G optical module design, power consumption is thus smaller. SFP has the high density, Video SFP the low power consumption, the lower system constructs the cost and so on the remarkable merit, the product widely uses the Gigabit Ethernet fiber communication domain, is the Universal module mainstream product. Video SFP F-tone can produce a full range of 10G SFP optical modules, including:
SFP 10GBASE-SR 300 m (multimode OM3 fiber);
SFP 10gbase-lrm multimode fiber 220 m;
SFP 10GBASE-LR Single-mode fiber 10-20 km;
SFP 10gbase-er Single-mode Fiber 40 km;
SFP 10GBASE-ZR Single-mode Fiber 80 km;
SFP 10GBASE-EZR Single-mode Fiber 120 km;
18 band CWDM SFP;
40 band DWDM SFP;
1, SFP has more compact size than X2 and XFP package (same as SFP size);
2, can and the same type of XFP, X2, Xenpak directly connected;
3, the cost is XFP, X2, Xenpak product is low.
The difference between SFP and SFP:
1, SFP and SFP look the same size;
2, SFP protocol specification: IEEE802.3, SFF-8472;
The difference between SFP and XFP:
1, SFP and XFP are 10G optical fiber modules, Video SFP and other types of 10G modules can be interoperability;
2, SFP than XFP appearance size is smaller;
3, because the smaller size SFP will signal modulation function, serial/solve string, Mac, clock and data Recovery (CDR), and electronic dispersion compensation (EDC) function from the module to the motherboard card;
4, XFP Compliance Agreement: XFP MSA Agreement;
5, SFP Compliant Protocol: IEEE $number 3ae, SFF-8431, SFF-8432;
6, SFP is more mainstream design.
7, SFP Protocol specification: IEEE $number 3ae, SFF-8431, SFF-8432.
