In this work, numerical simulations are performed and the performance comparison of four types of dispersion compensating Raman/EDF A hybrid amplifiers configurations in terms of gain, noise figure and nonlinear effect induced penalty is presented. A numerical simulator is presented for the analysis and design optimization of Raman/EDFA hybrid amplifiers for multi-wavelength operation. This simulator combines a steady-state model of a discrete Raman Amplifier (RA) with a spectrally resolved model for the Erbium Doped Fiber Amplifier (EDFA). The numerical simulator allows us to calculate the overall gain, the noise figure (NF), the optical signal-to-noise ratio (OSNR) and the signal and ASE spectrum at the output of a Raman/EDF A hybrid amplifier. We concluded that performance tradeoffs should be considered when an optimum hybrid amplifier configuration for a given fiber optic transmission system is to be decided.
