Abstract

Summary form only given. A comprehensive and accurate model of a Raman amplifier has been proposed. The model is based on measured spectra of the Raman gain coefficient and the fiber attenuation. The model includes a complete spectral ASE power distribution, temperature dependence, and Rayleigh scattering. A comparison between measured and calculated gain and noise performance shows agreement better than 0.1 dB. This model has been used to design the Raman amplifiers used in an error-free trans-Atlantic distance 10/spl times/10 Gbit/s wavelength-division multiplexed loop experiment.
