Table 3-416 GE optical interface attributes
Attribute Description
Connector type SFP
Standards compliance IEEE802.3z
Rate 1000 Mbit/s
Cable type Optical fiber (inserted in an optical module)
and
GE Optical Module
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 A 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.
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.
Table 3-417 lists the attributes of a 2.5GE optical interface.

DI/DO interface
A DI interface receives alarm input (9.6-60 V), and a DO interface sends output signals to
instruct an external device to perform required actions.
Table 3-418 lists the DI/DO interface
attributes.
