Generally if you want to go Fast Ether over single-mode fiber, you need
to use a pair of media converters.
For short distances, single-mode fiber may just happen to work with
the the "multi-mode" cards, the deal is that the coupling at either end
is so inefficient that you have little allowance left for fiber loss.
Some folks will deny that this is possible at all, but if you're
desparate or just need a temporary hookup, it doesn't take much work
to plug in the cable and try it.
Single-mode equipment over multi-mode fiber is another set of issues
and equipment such as the -LX GigE standard...
