GBIC (gigabit interface converter)
A transceiver that converts between electrical and optical signals for high-speed networking.
GBICs integrate the transmit and receive functions needed to convert between serial-electrical and serial-optical signals, simplifying switch and hub design.
The industry-driven GBIC specification defines a common form factor and electrical interface. This pluggable transceiver module lets system builders and net executives configure, incrementally populate and cost-effectively reconfigure fiber links as required. Initially targeted to support Fibre Channel data networks, the GBIC standard was quickly adapted for use with Gigabit Ethernet installations, as well.
By providing hot-swap interchangeability, GBIC modules give net administrators the ability to tailor transceiver costs, link distances and configure overall network topologies to their requirements. GBIC support also leaves the door open for changing the network without the wholesale replacement of system-level boards.
The use of GBIC transceiver modules reduces overall system deployment and inventory costs because a single form factor can be used for all transceivers. Network executives are not forced to buy fully populated switching equipment. They can purchase GBIC modules to configure their system incrementally, and the service/maintenance functions can be mixed and matched on the optical transceiver components on an as-needed basis.
