- These could be false alarms check the logs for the involved switches; look for similar messages , if any. Compare to direct measurements for db signal strength with info found in example links such as :
https://community.fs.com/blog/check-sfp-module-optical-signal-strength.html
https://www.cisco.com/c/en/us/support/docs/optical/synchronous-optical-network-sonet/16150-measure.html
