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.

NOTE
l In V200R008C30 and earlier versions, a combo interface works as an electrical interface and uses a
network cable to transmit and receive data by default.
l In V200R008C50 and later versions, a combo interface works in auto mode and automatically works as
an optical or electrical interface by default.
2.5GE optical interface
A 2.5GE optical interface supports GE/2.5GE auto-sensing and is used for data transmission
and receiving at over 1 Gbit/s.
