GE Bus {Gigabit Ethernet. Ethernet over fiber or twisted wire operating at 1000Mbps.}

Gigabit Ethernet {operates using either Shielded Twisted Pair [STP] copper, Un-Shielded Twisted Pair [UTP], CAT-5 copper or fiber cable. Also over a backplane at 1GHz.}

GigaBridge {PICMG 2.16 R1.0 is a PCI-switching technology developed by PLX Technology Inc. It runs on a scalable, self-healing ring topology supporting OC-12 to OC-48 trunk speeds. GigaBridge uses a 6.4-Gbit/s low-voltage differential signaling (LVDS) link interface.}

GMII Bus (Gigabit Media Independent Interface] Bus is an 8-wire chip-to-chip bus.
RGMII Bus, for Reduced Gigabit Media Independent Interface uses only 4-wires.

XGMII Bus uses SSTL_2 interface levels. provides an optional interconnection between the Media Access Control (MAC) sublayer and the Physical layer (PHY) of 10 Gigabit Ethernet. The interface provides two separate 32-bit data paths (TXD 31:0, RXD31:0) each with 4-bit data delimiters (TXC 3:0 , RXC 3:0) which are synchronous to their respective clock (TX_CLK, RX_CLK) and operate at 156.25 MHz ± 0.01%. GMII may be defined in the 802.3 standard.)

GPI Bus {Generic Packet Interfaces [GPI] Bus. GPI-8/16/32}

GPI/O {General Purpose input/Output is not a bus but a group of I/O extending out of a uP or Controller chip. GPI/O is not the same as the GPI bus.}

GPIB Bus {IEEE-488 Parallel Equipment Bus, Digital Interface for Programmable Instrumentation operates at 1MBytes/s over a maximum cable length of 20 meters.}

An alphabetic listing of released interface buses. Primarily the links describe the physical and electrical interfaces for the bus. Interface Bus protocols are not addressed.
