GBIC Modules

GBIC Modules: GBIC is short for GigaBit Interface Converter. It is an input/output transceiver used with one end to plug into a gigabit Ethernet port the other end of the transceiver is to connect the fiber optic patch cords and link the fiber optic networks. GBIC modules function is to transform the signals between the Ethernet network and fiber optic network. GBIC classification is based on its optical wavelength, data transmit rate, optical power, and the working distance. Generally GBIC fiber optic end the interface is SC type, the laser unit in GBIC module can be 850nm VCSEL, 1310nm FP, 1310nm DFB, and 1550nm DFB. GBIC modules are hot pluggable allowing a port to be changed from one type of external interface to another simply by plugging in a GBIC having the alternative external interface without having to power down the host switch/router.
