10base-FL was fiber optic. 

An older version was (as near as I can tell) FOIRL. I've got a box of
15 transcievers AUI<-->FOIRL that I'm having trouble using since I
have no AUI hub (MAU?). (Anyone want to sell me one?)

I have no idea if 10base-FL and FOIRL are interchangable in any 
circumstances.
