I don't get it.

So this faster-than-light, backward-traveling pulse only works in 
erbium-laced fiber?

""Einstein said information can't travel faster than light, and in this 
case, as with all fast-light experiments, no information is truly moving 
faster than light," says Boyd."

What does Mr. Boyd mean? You shine the laser onto the near end of the fiber, 
which creates a backward-going pulse on the opposite end -- how is that not 
transmitting information?
