We try to connect PTP550 with Mikrotik SFP (on both ends) and link are working, but Mikrotik CCR reports: FCS error on link ?
Anybody maybe can test this and report back is problem on Cambium or Mikrotik side ? Or general answer you must use Cambium SFP, but SFP is SFP, vendor free ?
It was observed Mikrotik Routers had the issue related to CRC errors with not the latest FW.
Please try to update FW on Mikrotik router.
In case the issue is still persist please open support ticket with Cambium Support Team.
Support ticket opened: Request #181795
Could you please try to upgrade your radios to the latest 4.3.2 FW and verify whether the issue still persists?
