Huawei switch connected to Huijue optical module

Ensure compatibility and certification when connecting a Huijue optical module to a Huawei switch, and verify port configuration and transceiver status for proper operation.

Compatibility and Certification

Huawei switches require optical modules that are certified for use on their devices. Non-certified modules, including third-party modules like Huijue, may not guarantee reliable transmission and could affect service stability. Huawei does not provide support for issues caused by non-certified modules . To check if a module is certified, look for the HUAWEI label, verify the manufacture date, or use the display transceiver command to check the Vendor Name field .

Port Configuration

1. Check interface status: Use the command display interface to see if the port is administratively up or down. If it shows Administratively DOWN, enable the port with the undo shutdown command .
2. Verify speed compatibility: Do not use a module with a higher rate than the interface supports (e.g., a 10G module on a 1G port) to avoid link failure .
3. Fiber type matching: Ensure single-mode modules are connected to single-mode fiber and multimode modules to multimode fiber. Mixing fiber types can prevent the link from coming up .

Monitoring and Troubleshooting

• Check transceiver parameters: Run display transceiver interface verbose to view wavelength, received, and transmitted optical power, which helps identify abnormal conditions .
• Loopback test: Connect the fiber jumper to the same module to test the port independently and confirm the module is functioning .
• Link status: Use display interface brief to see if the link is UP and monitor traffic statistics for errors .

Best Practices

• Prefer Huawei-certified modules for critical links to ensure stability and support.
• Avoid using modules with incompatible speeds or fiber types.
• Regularly monitor optical power levels and port statistics to detect early signs of failure.
• Contact Huawei technical support if using third-party modules like Huijue to confirm compatibility and receive guidance on configuration . By following these steps, you can maximize the likelihood that a Huijue optical module will operate correctly with a Huawei switch, while minimizing potential link issues.
