What is the switch / router module, which is simply to increase, extend or change the switch / router of some functions. .The different modules can provide different transmission rates, different modes, different linear (such as fiber optic module), and so on. .
SFP and GBIC fiber module GBIC, namely Giga Bitrate Interface Converter stands, is .Gigabit optical signal into electrical signal interface device. .GBIC is designed for hot use. .GBIC is an international standard interchangeable products. .Using GBIC Gigabit switch interface design flexibility as interchangeable in the market account for a large market share. . SFP, .SMALL FORM PLUGGABLE abbreviation that can be simply understood as the upgrade version GBIC. .SFP GBIC module module volume ratio reduced by half, the same panel can be configured in more than double the number of ports. .SFP Module GBIC same basic and other features. .Some switch vendors said the SFP module as small GBIC (MINI-GBIC). . fiber is divided into multi-mode fiber and single mode fiber are two: one, multi-mode optical fiber light-emitting device as simple cheaper and construction characteristics, widely used for short distance communication on the ., is divided into 50um multimode fiber core diameter and 62.5um core diameter two, which 62.5um the more common, but the performance is not good 50um. . .
