Transceiver Fiber to the Home. Tech moves fast! Stay ahead of the curve with Techopedia! The card had to be replaced with a potentially expensive one for the new media type. Once the server was powered up again, software may have needed reconfiguration as well. This process is often made faster, easier and more cost-effective by using a less-expensive GBIC.
The original media-specific Gigabit Interface Converter is unplugged while the server is running. The new GBIC is simply inserted in its place without shutting down or reconfiguring the system. Called SFF, it establishes a common electronic interface and a mechanical form factor for these devices. Originally written for a fiber channel converter design, the spec now includes Gigabit Ethernet-specific information as well. It also details algorithms to be used for GBIC management and error recovery.
Signals to and from the network card connector can also travel over this serial bus. On the network side, a transformer couples the transceiver signals to a Registered Jack 45 RJ45 connector. A fiber channel GBIC is similar, replacing media-specific components as appropriate. The transceiver, transformer and network-side connector would be different, for example.
