Huawei GE optical ports support SFP modules for 1 Gbit/s Ethernet, with options for combo interfaces and certified optical modules to ensure reliable operation.

Types of GE Optical Ports

Huawei switches provide GE SFP optical ports that can operate at 1 Gbit/s using SFP modules. Some switches feature combo interfaces, which include both an electrical (RJ45) port and an optical (SFP) port sharing a single forwarding interface. Only one of the two can be active at a time, and the mode can be switched according to network requirements .

Compatible Modules

• Certified Huawei SFP modules are recommended to ensure stability and full functionality. Non-certified modules may trigger alarms or cause intermittent link issues, and Huawei does not provide support for faults caused by non-certified modules .
• GE optical ports support 1000BASE-LX, 1000BASE-SX SFP modules, and some models also support GE copper modules or AOC cables in later software versions .
• To verify module certification, use the command display transceiver or check the Vendor Name field; certified modules display "HUAWEI" .

Configuration

For combo interfaces:

• By default, the interface operates in electrical mode.
• To switch to optical mode, enter interface view and execute: combo enable fiber
• To revert to electrical mode: undo combo enable fiber
• Ensure the same configuration is applied on the peer device to establish a link . For standard GE optical ports, simply insert a compatible SFP module and connect the fiber. Use display transceiver interface interface-type interface-number to view module details, including type, wavelength, transfer distance, and diagnostic monitoring status .

Monitoring and Troubleshooting

• Use display transceiver to check receive and transmit power, module type, and vendor information.
• If a non-certified module is installed, the switch may generate alarms such as hwOpticalUnAuthorized, and the interface may fluctuate between UP and DOWN states .
• Ensure proper insertion orientation for modules and verify that the fiber type matches the module specifications (single-mode or multi-mode).

Best Practices

• Always use Huawei-certified optical modules for GE ports to avoid service instability.
• For combo interfaces, only one port (optical or electrical) should be active at a time.
• Regularly monitor optical port statistics to detect potential issues early, including signal power and link status. By following these guidelines, Huawei GE optical ports can provide reliable 1 Gbit/s connectivity for enterprise networks, supporting both fiber and copper connections where applicable .
