Abstract
Abstract The study presents the average power model of optical Raman fiber amplifiers based on frequency spacing and amplifier section stage optimization technique. The amplifier section stage is taken from 25 to 75 km and frequency spacing is taken from 0.2 up to 1 nm. Input/output Raman signal variations are measured versus operating wavelength range and bit time period variations. The suitable input signal power for the optical transmitter is chosen to be −10 dBm and return to zero modulation code is applied with an available data rate of 10 Gb/s. Sixty-four channels are multiplexed to benefit a multi-number of users with suitable power levels.
