Interfaces named with `ge` represent what?

Question

I see a information:

Most interfaces are named according to:
 - Interface media type (ge, so, at, and so forth)
...

I know the so represent SONET, at represnet ATM, but how about the ge ? if it means the ethernet, why not et?

Answer 1

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.
