It would seem the SFP module you had does not support Digital Optical Monitoring (DOM). The data sheet for the MGBLX1 modules does not indicate DOM support.

as for as i see your SFP GUI recognised that means SFP oh technically speaking,
the Port not coming - it all depends on what device connected.
You can also Loop the Fibre TX and RX see the port come up for testing.
what is other end ?
you did not mentioned what cable you using MM or SM ?
