Gigabit Interface Converter

A gigabit interface converter (GBIC) is a standard for transceivers, commonly used with Gigabit Ethernet and fibre channel in the 1990s. By offering a standard, hot swappable electrical interface, one 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.

A variation of the GBIC called the small form-factor pluggable transceiver (SFP), also known as mini-GBIC, has the same functionality but in a smaller form factor. Announced in 2001, it largely made the GBIC obsolete.
