Many people do not know the difference between SFP+ and SFP, XFP, so it sometimes brings unnecessary trouble (security weak circuit). The 10G module has undergone development from 300Pin, XENPAK, X2, and XFP, and finally realized the transmission of a 10G signal in the same size as the SFP. This is SFP+. SFP+ meets the high density requirements of optical modules based on its advantages of miniaturization and low cost, and has gradually replaced XFP as the mainstream of the 10G market.
Difference between SFP+ and SFP, XFPSFP package - hot-swappable small package module, the current maximum rate up to 4G, more use of LC interface.
SFP+ package---standard package, working rate is 10G, can meet the Ethernet 10G application.
XFP Package - A standardized package for serial 10G optical transceiver modules.
SFP+ optical module advantages:
1. SFP+ has a more compact form factor than the X2 and XFP packages (same size as SFP);
2, can be directly connected with the same type of XFP, X2, XENPAK;
3, the cost is lower than XFP, X2, XENPAK products.
1, SFP and SFP+ have the same appearance size;
2. The maximum rate of SFP is up to 4G, and the rate of SFP+ is 10G.
3, SFP protocol specification: IEEE802.3, SFF-8472;
4, SFP+ supports digital diagnosis.
The difference between SFP+ and XFP1. Both SFP+ and XFP are 10G fiber modules and can communicate with other types of 10G modules.
2, SFP+ is smaller than XFP;
3, because of the smaller size, SFP+ will signal modulation function, serializer / deserializer, 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 + comply with the agreement: IEEE 802.3ae, SFF-8431, SFF-8432;
6. SFP+ is a more mainstream design;
7. SFP+ protocol specification: IEEE 802.3ae, SFF-8431, SFF-8432.
SFP is the abbreviation of SMALL FORM PLUGGABLE and can be simply understood as an upgraded version of GBIC. The SFP module is half the size of the GBIC module and can be configured with more than double the number of ports on the same panel. The other functions of the SFP module are basically the same as those of the GBIC. (Text and graphic knowledge of fiber optic modules)
Some switch vendors call the SFP module a miniaturized GBIC (MINI-GBIC). The SFP module is half the size of the GBIC module and can be configured with more than double the number of ports on the same panel. The other functions of the SFP module are basically the same as those of the GBIC. (Mini-GBIC). The acronym for Gigabit Interface Converter is an interface device that converts Gigabit electrical signals into optical signals. GBIC is designed to be hot swappable. GBIC is an interchangeable product that meets international standards. The Gigabit switch with GBIC interface design has a large market share due to its flexibility in exchange.
SFP standardizationSFP transceivers are regulated by a Multilateral Agreement (MSA) between competing vendors. The SFP is designed according to the GBIC interface, allowing a larger port density than the GBIC (number of transceivers per inch on the main board side), so the SFP is also called "mini-GBIC." The related SFF transceiver is smaller in size than the SFP, but the SFF is soldered as a pin through-hole device to the motherboard instead of to the edge card slot. on.
SFP typeSFP transceivers have a variety of different transmit and receive types, and the user can select the appropriate transceiver for each link to provide the "optical performance" that can be achieved based on the type of fiber available, such as multimode fiber or single-mode fiber. The available optical SFP modules are generally classified into the following categories: 850 nm wavelength/550 m distance MMF (SX), 1310 nm wavelength/10 km distance SMF (LX), 1550 nm wavelength/40 km distance XD, 80 km distance ZX, 120 km away from EX or EZX, and DWDM.
The SFP transceiver also provides a copper interface so that host devices designed primarily for fiber communications can also communicate over UTP network cables. Wavelength-division multiplexing (CWDM) and single-fiber "bidirectional" (1310/1490 nm wavelength uplink/downlink) SFPs also exist. (Text and graphic knowledge of fiber optic modules)
XFP (10 Gigabit Sma Form Factor Factor) is a hot-swappable optical transceiver that is independent of the communication protocol. It usually transmits light at a wavelength of 850nm, 1310nm, or 1550nm, and is used for SONET/SDH at 10G bps. Fibre Channel Gigabit Ethernet, 10 gigabit Ethernet and other applications also include DWDM links. The XFP contains a digital diagnostics module similar to SFF-8472, but has been extended to provide a powerful diagnostic tool.
