Comparison Of Single-Pump Fopa And Raman Assisted Fopa Performance In A 16 Channel Dwdm Transmission System

In this paper the authors implement a Raman assisted fiber optical parametric amplifier solution and compare the its configuration with the configuration obtained for a standard single-pump parametric amplifier that ensured approximately the same level of amplification. The simulation results are obtained in a 16 channel dense wavelength multiplexed transmission system with intensity on-off keying modulation and 50 GHz channel spacing. Both amplifiers are used as preamplifiers in the transmission system under attention. While comparing the amplifiers the main focus is on the total amount of power required for the amplifier to ensure a certain level of amplification, and the quality of the amplified signal.
