The three options mentioned are rather generic terms, not really specific to the optical designspace. Generally, you want a repeater, when you talk fiber optics. These devices will "square-up" the pulses, and increase the signal amplitude for the following run of fiber. Thannara's comment about EDFA's is spot on; they are very commonly used devices for repeaters.
