GE combo interface
A GE combo interface consists of an optical Ethernet interface and an electrical Ethernet
interface on the panel. The two interfaces have only one internal forwarding interface. The
electrical and optical interfaces are multiplexed, and only one of them can work at a time.
When one of the Ethernet interfaces is working, the other interface is shut down.
l
The GE electrical interface (10/100/1000 Mbit/s auto-sensing) transmits and receives
services at 10 Mbit/s, 100 Mbit/s, or 1000 Mbit/s.
l
The GE optical interface (100/1000 Mbit/s auto-sensing) transmits and receives services
at 100 Mbit/s or 1000 Mbit/s.
DO interface
The DO interface provides output signals to instruct the connected device to perform required
actions.
