Dears,

I want to ask about smth critical I've faced lately regarding error seconds and severity errors, i've span with below details:

STM64 connection with 67 KM long ,, and the received power from one side is -23 dBm and the other is -18 dBm,see below, the errors shown on the transmit/receive directions:

 

power span:

 

what is the probable cause of these errors as we've changed the local patches and SFPs with ODF with no luck? is it a card failure and how to isolate the issue?

 

Thanks in Advance,

 

Best,

Mohammad
