How Can I View Optical Power Information?

If non-Huawei-certified optical modules are used, the system may be unable to obtain the correct information. You are advised to use Huawei-certified optical modules.

Run the display transceiver interface interface-type interface-number verbose command to view power information of a specified optical module.

The optical power is normal when it is between the upper and lower thresholds. If the optical power exceeds the upper threshold, a high optical power alarm is generated. If the optical power falls below the lower threshold, a low optical power alarm is generated.
