Gigabit interface converter
Gigabit interface converter (GBIC) is a standard for transceivers. First defined in 1995, it was used with Gigabit Ethernet and Fibre Channel. By standardizing on a hot swappable electrical interface, a single gigabit port can support a wide range of physical media, from copper to long-wave single-mode optical fiber, at lengths of hundreds of kilometers.
The Small Form-factor Pluggable (SFP) transceiver, also known as mini-GBIC, succeeds GBIC. Announced in 2001, it obsoleted GBIC.
