Checking Optical Power on Huawei Switch Ports

Use the display transceiver verbose command to view both transmit (TX) and receive (RX) optical power for Huawei switch ports.Viewing Optical Module InformationTo check the optical power of a specific port on a Huawei switch:Display all optical modules: Run display transceiver to view general information for all optical ports, including module type, wavelength, and vendor details .Display a specific port: Use display transceiver interface to view information for a particular port. Replace and with the port type and ID .View detailed diagnostic information: Add the verbose parameter to see transmit and receive power:CodeCopydisplay transceiver interface verbose The output includes:TX Power (dBm): Transmit power of the optical moduleRX Power (dBm): Receive power of the optical moduleHigh and low thresholds for both TX and RX powerTemperature, voltage, and bias current of the module Example OutputCodeCopyTransceiver Type :1000_BASE_SX_SFPConnector Type :LCWavelength(nm) :850Digital Diagnostic Monitoring :YESVendor Name :FINISAR CORP.RX Power(dBm) :-7.26RX Power High Threshold(dBm) :0.00RX Power Low Threshold(dBm) :-16.99TX Power(dBm) :-4.47TX Power High Threshold(dBm) :0.00TX Power Low Threshold(dBm) :-9.50 TX Power indicates the signal strength being sent from the port.RX Power indicates the signal strength received at the port.Values outside the high/low thresholds may indicate fiber issues, dirty connectors, or faulty modules .Additional TipsEnsure that both local and remote optical modules have the same wavelength to avoid link issues .If optical power is too low or too high, check fiber connections, clean connectors, or replace the optical module if necessary .Use display interface to verify link status and traffic statistics alongside optical power . By following these commands, you can effectively monitor the optical power and overall health of Huawei switch ports, helping to diagnose and prevent connectivity issues.
