Your problem is that you're operating below the warning threshold level for optical receive power. -13.0 dBm received and the threshold is -9.9.

You need to go through the path and clean your connectors and possibly replace any marginal jumpers. If that fails, you can try moving the path to another pair of fiber with less loss. You should have OM3-rated fiber or better end to end.

I have the same issue but my interface is not connected and it's down, is there any reason that I still receive this alerts?  

If there is no link you can remove the transceiver or shutdown the port.

If there is supposed to be a link you may need to swap one or more transceiver assuming you did what @Marvin Rhoads suggested.

If that fails you might have a broken fibre in which case you might need to recertify the fibre.

Most of the time cleaning the end works.
