A GBIC (Gigabit Interface Converter) is a standard for optical transceivers. A GBIC is commonly used with Gigabit Ethernet and Fiber channel.
A GBIC will offer a standard, hot swappable electrical interface and with GBIC, one gigabit Ethernet port can support a wide range of physical media, from copper to long-wave single-mode optical fiber, and GBIC supports lengths of hundreds of kilometers. This means a GBIC is very flexible in use.
The advantages of GBIC (gigabit interface converter) Transceivers
The main advantage of GBIC transceivers over non GBIC or fixed transceivers is that GBIC transceivers offer greater flexibility when used in applications where a GBIC is most appropriate.
A GBIC optical transceiver is hot-swappable, making a GBIC invaluable where critical systems are involved.
GBIC follows a non-proprietary standard as defined by SFP for GBIC.
Variations of GBIC
A GBIC may also be known as a Mini-GBIC or SFP. A Mini-GBIC or SFP is essentially the same as a GBIC, but is in a smaller form factor.
