SFP Adapts To The Rapid Development Of The Network

- Sep 18, 2017 -


SFP is an abbreviation for Small Form-Factor Pluggable and can be easily understood as an upgraded version of GBIC. SFP volume is less than half the GBIC module, and more than twice the number of ports can be configured on the same panel. SFP's other features are basically the same as GBIC. Some switch manufacturers said SFP for small GBIC (MINI-GBIC), support SX, LX, TX, LH, take 1000M.

SFP is understood as an upgraded version of GBIC. SFP (which is half the size of the GBIC module and can be configured with more than double the number of ports on the same panel. Video SFP Since the SFP is basically the same as the GBIC function, it is also known by some switch manufacturers as miniaturized GBIC (Mini-GBIC ).

SFP compresses the size and power consumption by placing CDR and electro-dispersion compensation outside the module.

SFP products are relatively late optical modules, but are also the most widely used optical module products.

SFP (Small Form-factor Pluggables) Many people understand it as an upgraded version of GBIC. SFP volume is reduced by at least half of the GBIC optical module, Video SFP and more than twice the number of ports can be configured on the same panel. As the SFP in function and GBIC basically the same, therefore, some switch manufacturers are also known as miniaturized GBIC (Mini-GBIC).

SFP development

GBIC and SFF in the development of optical modules have had a very extraordinary history, Video SFP with the rapid development of the network, they are gradually replaced by SFP.

SFP is the development of SFF and GBIC optical modules, because SFF and GBIC is 1X9 optical module after the two directions of the development of products, have their own advantages: miniaturization and hot swap.

SFP optical module inherited the GBIC hot-swappable features, but also learn from the advantages of SFF miniaturization. Using LC head, the volume is only GBIC module 1/2 to 1/3, Video SFP greatly increasing the port density of network equipment to adapt to the rapid development of the network trend, so get the most extensive application, the main Equipment manufacturers, without exception, Video SFP to abandon the GBIC products, only use SFP optical module products. As a result of a unified standard, the manufacturers of SFP products can be compatible, SFP products can be used as a separate network equipment procurement.

Although there have been many higher-tech, updated optical module products, but SFP will continue to exist for a long time. After the SFP, the development of optical modules is mainly toward a higher rate of development, Video SFP now has appeared 10G, 40G, 100G and other optical modules. Which SFP + optical module is believed to be widely used after SFP generation of products.
