Huawei checks optical module optical power

Fiber and communications infrastructure knowledge brief Published 02 Jan 2024

Use this reference to prepare product questions for BAGYOU FIBRE. Check interfaces, capacity, protection and installation requirements against the current product documentation.

Use Huawei commands like display transceiver verbose or display transceiver diagnosis to view the transmit (TX) and receive (RX) optical power of optical modules.

Checking Optical Module Power

Access the Huawei device CLI: Log in to the switch, router, or optical device where the module is installed. Ensure you have the necessary privileges to run diagnostic commands. Identify the interface: Determine the interface where the optical module is installed.

You can list all interfaces using: display interface brief This shows interface types, numbers, and link status, helping you locate the module. View module information: Run the command: display transceiver [interface interface-type interface-number | slot slot-id] The verbose option provides detailed diagnostic information. This command displays TX Power (dBm) for transmit power and RX Power (dBm) for receive power, along with other parameters like temperature, voltage, and bias current.

Check diagnostic information: For more detailed monitoring, use: display transceiver diagnosis interface [interface-type interface-number] This shows Digital Diagnostic Monitoring (DDM) data, including current RX/TX power, high/low thresholds, and module health status. Understanding the OutputTX Power (dBm): Indicates the optical power being transmitted by the module. Ensure it is within the module's specified range.

R

X Power (dBm): Indicates the optical power received by the module. Values outside the acceptable range may indicate fiber loss, connector issues, or module faults. Temperature, Voltage, Bias Current: Monitoring these ensures the module operates within safe limits.

Example OutputCodeCopyTransceiver Type: 10GBASE_LR_SFPConnector Type: LCWavelength(nm): 1310Digital Diagnostic Monitoring: YESTemperature(°C): 37. 77Voltage(V): 3. 28Bias Current(mA): 38.

46RX Power(dBm): -2. 97TX Power(dBm): -2. 40 This output shows the module's real-time operating status, including optical power levels, which can be used for troubleshooting or verifying link quality.

Tips

Always use Huawei-certified optical modules to avoid compatibility and data bus issues. Compare RX/TX power against the module's high/low thresholds to detect abnormal conditions. For high-speed modules like 400GE, similar commands (display optical-module base information interface) can be used to check TX/RX power.

By following these steps, you can effectively monitor and verify the optical power of Huawei optical modules, ensuring reliable network performance.
