This study has clarified the optical fiber signal strength based on Raman fiber optic amplifiers schemes in dense wavelength multiplexed communication systems. The signal power with, without Amplification in various pumping configurations scheme is studied with propagation distance variations. The bidirectional pumping power configuration based various pump power is analyzed with propagation distance variations. Amplified forward signal power for various fiber types is investigated with propagation distance variations. These fibers are used such as single mode (SM)-28 fiber, non-zero dispersion shifted fiber (NZDSF), truewave reach fiber for the efficient employment in fiber systems. Amplified bidirectional signal power for various both pump power and fiber types are clarified with propagation distance variations. The pumping power configurations scheme variations are demonstrated with propagation distance variations. Forward/backward pumping power configuration direction variations are investigated and clarified with propagation distance variations for various pumping power values.
