I am having FCS error problems on my Mikrotik SFP+ optical port, I have tested with my business service provider and everything is fine.
But on my Mikrotik side it is throwing FCS type errors in log, I have changed the SFP+ 3 times to rule out that it is not an incompatibility problem.
Please help, when these errors occur they cause me to lose packets on my internet link.
I tried with a 10gtek module and now I tried with a Cisco-Prolabs module... when the FCS errors occur the link drops and I lose connectivity with my provider, on the other end of my internet provider there is also a Cisco Prolabs SFP+ module SFPPLR31-10-CJ.
My mikrotik is CCR1009-8G-1G-1S-1S+
SFP+ 10G
I already tried to turn off the autonegotiation, force it to 10G only but the problem persists.
