Check the optical module power on 5608t

You can check the optical module power on a Huawei MA5608T OLT using CLI commands to display TX/RX power, temperature, and bias current of the SFP/XFP transceivers.Steps to Check Optical Module PowerAccess the OLT CLIConnect to the MA5608T via console, SSH, or Telnet.Log in with administrative credentials.Identify the InterfaceDetermine the port where the optical module is installed (e.g., GPON port or GE/FE P2P port).Run the Display CommandUse the command:CodeCopydisplay interface Example:CodeCopydisplay interface gpon 0/1 This command shows the link status, transceiver type, and traffic statistics.Check Optical ParametersLook for the following fields in the output:TX Power (dBm) – the transmit power of the module.RX Power (dBm) – the received optical power.Bias Current (mA) – the current driving the laser.Temperature (°C) – module temperature.Ensure the values are within the acceptable thresholds for the module type (e.g., Class B+ or Class C+ SFP/XFP) as specified in the MA5608T documentation .Optional: Display All PortsTo view all interfaces at once:CodeCopydisplay interface brief This provides a summary of all ports, including link status and transceiver type.Notes and TipsNormal RX/TX power ranges depend on the optical module class. For example, a Class B+ GPON SFP typically has TX power between 0.5 dBm and 5 dBm, and RX power between -27 dBm and -8 dBm.Troubleshooting: If RX power is too low or TX power is abnormal, check fiber connections, module seating, or replace the transceiver.Monitoring: Regularly check optical power to prevent service degradation and detect early faults. By following these steps, you can effectively monitor the optical module power and ensure proper operation of your Huawei MA5608T OLT .
