In this section a large selection of GBIC (GigaBit Interface Converter) and miniGBIC (SFP) high performance optical modules can be found. GBIC is the first form of pluggable Giga optical modules, being available only for dual fiber or WDM single strand fiber. SFP(Small Form Pluggable) modules are the latest and most used form of optical modules and are also in dual fiber, WDM single strand and special CWDM optical wavelengths.
