In this project, the characterization of L-band Raman amplifier by utilizing Non Zero Dispersion Shifted Fibre LEAF ® optical fiber was studied. The effect of Stimulated Raman Scattering effect was observed upon injection of various Raman pump unit power and laser sources power to the system. Based on the experiment, it shows that at 1584.89 mW and 1778.27 mW, the RPU power at 1480 nm was oscillated to the L-band wavelength region at 1580 nm. Maximum output peak power was found at injected RPU power of 1584.89 mW. Meanwhile, at 1580 nm injected laser source power of 0.04 mW, 0.4 mW, 1.58 mW and 2. 51 mW, the amplified power was obtained at 0.36 mW, 2.54 mW, 3.0 mW and 3.65 mW. Furthermore, the variation of RPU power and laser power value affect the amplification of peak power whereby the maximum value of power led to the increment of peak power.
