How Can I View the Optical Module Wavelength?

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

The wavelength of the local and remote ends must be the same. You are advised to use Huawei-certified optical modules of the same type.

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