Short for
gigabit interface converter, a
transceiver that 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.
A GBIC allows designers to design one type of device that can be adapted for either optical or copper applications. GBICs also are hot-swappable, which adds to the ease of upgrading electro-optical communication networks.
