Really hope someone can shed some some light?
When connecting to a unfi edgeswitch 12 fibre on the SFP plus port we don't receive traffic but only send.
If we move the module from plus port to any other sfp port, link is established and all works.
Disabled auto neg forced to 1G and disable and enable to no avail.
Even tested into Netgear sfp switch but results in the same outcome.
Any ideas?

CCR1016-12S-1S+ has "sfpplus1" cage, not "sfp-sfpplus1", so it can only work with "SFP+" modules, and not "SFP" modules, that might be related to your problem.

Thanks for the info.
I have a sfp+ module in the sfpplus1 cage.
If I loop from the sfpplus1 to any other sfp on the mikrotik I get llink.
Just not to another sfp on another device.
