Performance of a single-channel fiber-optic transmission system in which signal regenerators are periodically inserted is analyzed in terms of information rate (IR) considering channel memory. Limitations in using regenerators in a system having non-zero residual dispersion between the regenerators are discussed. It is shown that a type of signal impairment caused by the interaction between the transmission-fiber dispersion and the regenerator nonlinearity is pattern-dependent and will be mitigated by the use of sequence estimation after detection at the receiver.
