We use this setup a lot, it works fine for us.  Make sure that the SQE on
the fiber transceivers is turned off.  Use the lower power level.  Build
a dummy network at the repeater end to make sure you aren't seeing a 
problem from the remote Ethernet passing through the fiber link.  Beg, borrow
or steal an OTDR long enough to make sure that the whole fiber path works
correctly, you could have a bad ST barrel.  Make sure there are no grouding
problems at the remote end.
