Dear friend!
Please refer to the following information
Cause 1: The receive optical power of the board is close to the critical value.
You are advised to check the optical cable attenuation and fiber connections inside the site to check whether the optical cable attenuation is large or the optical fiber connection is loose.
Cause 2: The hardware is faulty.
You can compare the optical module with the board of the same model. If the optical module or board is faulty, replace the hardware.
Thank you!

If the R_LOS alarm or other critical alarms exist, clear the alarms first.
