The Gigabit Interface Converter (GBIC) is an integrated fiber optic transceiver that provides a high-speed serial link from a port or slot to the network. The GBIC transceiver module is a bidirectional device with a transmitter and receiver in the same physical package. This transceiver converts serial electric signals to serial optical signals and vice versa. In networking, a GBIC is used to interface a fiber optic system with an Ethernet system, such as Fibre Channel and Gigabit Ethernet.
