Clean the optics and clean the patch cable.

I've seen many messages of this type when the SFP is non Cisco.

Hi Liviu,
All SFPs are Cisco and it's alert are showing last few days.
Without any type of network activity in the whole network.

Is this Interface up and working ?
check the Physical cables and also how is the environment temperature ?
Try replacing the SFP with another SFP and test it
Still issue try upgrade to latest code 17.6.X onwards and check.

Hello @cmishra ,
the Optical Receive Power of interface Te2/1/5 is -9.8 dBm and the warning threshold of the interface is set at -9.9 dBm. It's not the end of the world as the interface counters are clean.
Do you have a similar interface with the same SFP and a similar FO cable run? Can you look at and share the show interface Te... transceiver detail of that interface for comparison?
