Common generations of modules: GBIC - the first generation of Gigabit optical interface converters. SFP - Small Form-factor Pluggable, or “mini-GBIC. ” XFP - an early 10 G standard, larger and now obsolete. Optical and copper models can be used on a wide variety of Cisco. A GBIC (Gigabit Interface Converter) is a hot-swappable input/output device that connects a Gigabit Ethernet port to a network with an electrical interface on one end and an SC or LC connector on the other. Installed in switch or router ports, transceivers enable fiber-based communication between network devices. Key characteristics include: Speed: 1 Gbps, 10 Gbps, 25 Gbps, or higher. The most. They support various types of fiber optic protocols such as Ethernet at gigabit speeds, Fiber Channel (FC), or SONET/SDH, among others, which can operate over long distances without much signal decay, thus making them perfect not only for enterprise networks but also service provider.
