Distributed amplification in fiber-optic transmission systems is quantitatively studied. Optimization techniques to find amplifier parameters that maximize system performance are discussed. A particular emphasis is given to noise properties of Raman amplifiers and a tradeoff between the noise performance and nonlinear impairments. It is shown that Raman amplification in dispersion-managed fibers closely approaches the theoretical limit of an ideal distributed amplifier and further increases the system reach. Recent advances in the Raman-assisted ultra-long-haul transmission are briefly reviewed.
