You weren't using the same standards. Right off the bat, 1000Base-FX doesn't exist. 100Base-FX does however.

If you were in the gigabit over fiber world, your 1350nm side was 1000Base-LX or 1000Base-LX10. The 850nm side was 1000Base-SX.

SX is more common, but LX can be pushed MUCH further distances, at least over single mode.
