Huijue checks optical module parameters

Use the display transceiver command on Huijue switches to view optical module parameters, including wavelength, transmission distance, fiber type, and optical power.

Step-by-Step Guide

1. Log in to the Switch Access the Huijue switch via Telnet, SSH, or console port. Ensure you have administrative privileges to run diagnostic commands . 2. Identify the Switch Model Run the command:

display device

This shows the switch model, which helps determine the supported optical module types . 3. Check Supported Optical Modules Refer to the Hardware Description or the "Pluggable Modules for Interfaces" section for your switch model to see compatible optical modules, including single-mode or multi-mode types . 4. View All Optical Module Parameters Execute:

display transceiver

This command displays information for all optical ports, including:

• Center wavelength
• Transmission distance
• Fiber types supported
• Receive optical power
• Transmit optical power
• Vendor and manufacturing information
• Alarm status for optical power thresholds 5. View Parameters for a Specific Port To check a specific interface, use:

display transceiver interface interface-type interface-number

Replace interface-type and interface-number with the actual port details. This provides detailed diagnostics for that port, including real-time optical power and threshold alarms . 6. Monitor Optical Power Thresholds Check the diagnostic information for receive and transmit power. Typical thresholds may range from -3 dBm to -23 dBm. Set alarms to notify if power exceeds these limits . 7. Troubleshoot if Needed

• If optical power is low or abnormal, verify the module is Huijue-certified.
• Inspect fiber connections, clean connectors, or replace the module if necessary . 8. Optional: Use Optical Multimeter (OMM) For advanced diagnostics, an OMM can measure optical power, attenuation, and wavelength directly, complementing the switch's built-in commands . By following these steps, you can effectively view and monitor Huijue optical module parameters, ensuring proper operation and facilitating troubleshooting.
