Yes, there are.  (I use fiber 1- and 10-gigabit extensively  
(especially the latter) at my work.)

Interestingly, the IEEE proposals out there for 40-gigabit and 100- 
gigabit talk about ganging 4 or 10 10-gigabit *fiber* connections  
together -- I would have thought that they could just use multiple  
colors (frequencies) over the *single* fiber without interference,  
using prisms to join/split the colors.  Or am I being way too  
simplistic?
