In this thesis, we investigate the design and amplification characteristics of discrete fiber Raman amplifier (FRA), and discuss with amplification characteristics of FRA by employing multi-pumping-wavelength configuration. Recently, because of the invention of high output power of pump laser diodes, so discrete FRA can be practically employed in optical fiber communication system. The fiber Raman amplifier has two merits. One is the low noise characteristic and the other is the arbitrary spectral gain band, so it will play an important role in optical communication system. In this study, we employ backward pumping configurations in the experiment and simulation of discrete FRA. By comparing with results of experiment and simulation, we prove that the simulation results quite agree with the experimental data of four pumping wavelengths configuration, we have successfully designed an L-band gain flattened discrete FRA by using four pumping wavelengths configuration. The experimental results showed that the amplifier, for the input of seven optical channel each with ¡V16 dBm input power level, has an optical gain of >10 dB of each channel with good gain uniformity (<1 dB) in the 1565-1595 nm wavelength region.
