Fibre help!

Did it work now? Is the problem the SFP / SFP+ module's compatibility? I have ever bought the fiber modules from some third party manufacturers which function not well as expected, too. It was bad shopping experience!

My bad experience was paying over £200 each to begin with for genuine ones, then they failed....and only later did I discover that cheap ones not only worked as well - but they didn't break down.

Are you sure the modules that you have bought are compatible with the UBNT switch? Have you checked the compatibility list? https://help.ubnt.com/hc/en-us/articles/205220850-EdgeSwitch-Which-SFPs-are-compatible-with-the-EdgeSwitch- https://help.ubnt.com/hc/en-us/articles/212561258-UniFi-Which-SFPs-can-I-use-with-UniFi-switch
