I'm using Omada Controller and TL-SG2210P, it also has two SFP ports and on controller UI, it just shows up like other Ethernet ports. So currently I did not connect anything to SFP port and it shows link down.

  @Somnus Yes I have the same, but we need to have the optical output in dbm...

llike this:

This usefull to eliminate fibre issue...

It's not available on the controller or web interface. In old days there was a CLI command that can show all SFP status but I can't remember it was which command.

I think you can send this requirement to Request&Suggestions block.
