	We have had mixed results depending which match up with what
our 3rd party optics supplier has told us as well.  They will sell us
generic tri-rate copper SFPs but recommend against using theirs unless
you test each use-case specifically.

	We've seen the software report link-up when there is nothing
connected to the SFP in using genuine Cisco SFP-T optics in the EX
boxes.


TL;DR

	It will work, but you may not get link fault data.
