Unstable 10Gbit connection of Mikrotik CSS326-24G-2S+RM with Mikrotik S+RJ10 SFP

I use one ASUS XG-C100C network card in each of two PCs that are connected to Mikrotik CSS326-24G-2S+RM (each via Mikrotik S+RJ10 SFP).



One PC is very close (2 meter Cat5E cable), the other is far (15 meter Cat5E cable). I get brilliant 10Gbit speed on both links. Everything works fine until I even slightly touch SFP+ module or RJ-45 connector. If not touched, links work brilliant at least for a month without problems (have not tested longer yet). If touched, link immediately goed down and then random interruptions start to occur. Next interruption can happen in several minutes or in several hours - unpredictable.



I use latest RouterOS and firmware. The only thing that seems to help - I try to insert connectors with SFP+ modules more strongly (firmly) into the SFP+ ports, but this seems strange and unstable, because even a slight touch can break connection again.



What am I doing wrong? Any suggestions?
