    PERFORMANCE ANALYSIS OF DENSE WAVELENGTH DIVISION MULTIPLEXING (DWDM) USING DIFFERENT OPTICAL AMPLIFIERS IN OPTICAL FIBER TECHNIQUES
    (Department of Physics, Nasrawa State University, Keffi., 2017-11-11) Husseini, Umar Arafat
    In this research work, we analyzed the performance of Dense Wavelength Division Multiplexing (DWDM) using different optical amplifiers. DWDM systems consist of 120 channels having 0.25 nm channel spacing using RAMAN amplifier, Erbium Doped Fiber Amplifier (EDFA). The length of the RAMAN, EDFA amplifier are varying from 14.5 m to 20.5 m. Due to our observation, we conclude that the Gain increases as the length of amplifier increases in the EDFA, it gives better results as compare to the RAMAN. The gain flatness is more in RAMAN amplifier as compare to EDFA amplifiers.
