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 the GBIC. (Graphic knowledge of fiber optic modules)

Some switch manufacturers 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 the GBIC. (Mini- GBIC). Abbreviation for Gigabit Interface Converter, an interface device that converts gigabit electrical signals into optical signals. The GBIC can be designed for hot swapping. GBIC is an interchangeable product that meets international standards. Gigabit switches designed with GBIC interface have a large market share in the market due to flexible interchangeability.
