I guess you're asking about JunOS, the Operating System of Juniper for their hardware.

ge means Gigabit Ethernet.

This a list of ethernet interfaces and names used in JunOS:

ae— Aggregated Ethernet interface.

et— 100-Gigabit Ethernet interfaces.

fe— Fast Ethernet interface.

ge— Gigabit Ethernet interface.

xe— 10-Gigabit Ethernet interface.

G is mainly represent the Bandwidth of port/interface that means 1000 Mega bits per seconds where as E for Ethernet technology. So, port name written as Gigabit Ethernet as per IEEE standards, Now 10GE and 100GE interfaces are also deployed in production environment.
