I've had the same problem, connecting multimode NICs to a singlemode switch. This was all in one room so I just used multimode fiber from the NIC to the switch and whatever fiber with an attenuator ($50) in the other direction. It was a trial and error thing but it's working now for over two years without any problem. You might have a problem in the NIC to outside direction. Connecting MM fiber to SM fiber will loose almost all of the signal but it might work if you use single mode fiber up to the NIC and use as little as possible connectors (they all loose some signal). -- Wim Livens.
