SFP many people interpret it as an upgraded version of the Gbic. The SFP optical module is reduced by at least half the volume of the Gbic light module, and can be configured on the same panel for more than 1 time times the number of ports. Because the SFP is functionally consistent with the GBIC, Video SFP it is also known as a miniature GBIC (mini-gbic) by some switch vendors.
SFP is the development of SFF and gbic light module, because SFF and gbic are the products of two directions after 1x9 light module, have their own advantages: miniaturization and hot-swappable.
SFP inherits the hot-swappable properties of the Gbic, and also draws on the advantages of SFF miniaturization. Using LC Head, the volume of the Gbic module is only 1/2 to 1/3, Video SFP greatly increased the network equipment port density, adapt to the rapid development of the network trend, so it has been the most extensive application, at present the main equipment manufacturers, without exception to abandon the Gbic products, Video SFP only use SFP optical module products. As a result of the adoption of a unified standard, manufacturers of SFP products can be compatible, SFP products can be used as a separate network equipment procurement.
Although there have been many higher technology and newer optical module products, SFP optical modules will continue to exist for a long time. After the SFP, Video SFP the development of the optical module is mainly toward a higher rate of development, now has appeared 10G, 40G, 100G and other optical modules. The + optical module is believed to be a generation of products that are widely used after SFP.
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. 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;
