Sam..

How long are your fiber jumpers (patch cords I'll assume)??
You may know this but there is a thing called a sunburst effect that
ocures on short fiber runs (or so I've been told). I've been told
9 foot is the shortest you should run. I've used 12 foot to be
safe..

Your problem may indeed be driver related but I thought I'ed throw 
this little piece of info out.
