SFP optical module concept

SFP (Small Form factor - Pluggables) many people bring their understanding for the GBIC upgrade version.SFP optical module GBIC module at least half light, the ratio of volume can be configured on the same panel more than more than double the number of ports.Due to the SFP modules on the function and the GBIC, therefore, also some switches manufacturer called miniaturization GBIC (Mini - GBIC).

The development of the SFP optical module

SFF and GBIC module in the process of development have very special history, with the rapid development of network, they are gradually replaced by the SFP optical module.

SFP optical module, the development of SFF and module GBIC light because of SFF and module GBIC is 1 x9 light after two direction of products, have their own advantages: miniaturization and hot plug.

Inherited the SFP optical module GBIC hotplug characteristics, also draw lessons from the SFF miniaturization advantage.By LC, the volume is only 1/2 to 1/3 of the GBIC module, greatly increased the port density of network equipments, adapt to the trend of rapid development of network, so has been the most widely fan used, the main equipment manufacturers, with no exception to discard the GBIC products, only USES the SFP optical module products.Due to adopt a unified standard, each manufacturer of SFP product can be compatible, SFP products can be used as a single network equipment procurement.

Although at present there have been many higher technology, update of light module products, but the SFP optical module will continue to exist for a long time.After the SFP optical module development mainly toward a higher rate of development, now has 10 g, 40 g to 100 g optical module, etc.After the SFP + light module believe SFP is widely used a generation of products.
