Optical infrastructure needs are increasing in parallel with the development of communication technologies. Wavelength division multiplexing (WDM) systems have been developed and widely used to meet the increasing bus need. Optical amplifier systems play an important role in the transmission of optical signals over long distances in the use of WDM systems. For this reason, multipump distributed fiber Raman amplifiers are a good alternative. When designing distributed Raman amplifier systems, the power of the pump must be optimized along with a certain number of optical signals to be included in the optical fiber to flatten the gain of the signals in the transmission of optical signals over long distances. In this context, it was aimed to flatten the gain of 80 optical signals with an initial power value of 1mW as a result of 80 km transmission. For this, Raman gain coefficient and optical attenuation coefficient were first processed into the system as polynomials and made ready. Then, the constant terms were entered into the equation, and then all the equations were successfully adapted to the PSO algorithm. Afterwards, the PSO algorithm was operated for 4,5 and 6 pumps and optimum values were obtained. When the net gain differences are examined: +/- 3dB for 4 pumps, +/- 2dB for 5 pumps and +/- 1dB for 6 pumps are obtained. It is expected that better results will be obtained in parallel with the increase in the solution power of the optimization algorithms.
