An EDFA involves taking a weak arriving optical signal and combining it with a locally generated higher power optical signal in a length of fiber that has been doped with the erbium. The erbium atoms are excited by this action and they generate photons at the same phase and direction as the arriving signal.
Is that hot or what??

That is pretty cool, but what else did you expect a geek to say?
Happy holidays. =)
