A novel promoted parallel erbium doped fiber amplifier (PP-EDFA) is numerically demonstrated and investigated, for high capacity 95 x 40 Gb/s dense wavelength division multiplexing (DWDM) transmission system. The proposed PP-EDFA is used to achieve a flat gain over wideband within communication window. The amplifier consists of two sections of erbium-doped fiber (EDF) with a total length of 6 m and requires a total pump laser power of 195 mW. The results reveal that the amplifier has flat gain of 19.8 dB with a ripple of less than 1 dB, over broad bandwidth of 80 nm. The noise figure (NF) of proposed amplifier fluctuates between 3.1 and 5.2 dB, within bandwidth of 1520-1600 nm. In contrast with parallel EDFA (P-EDFA), the proposed PP-EDFA contributes to a higher and flatter gain, as well as it requires shorter EDFs and lower pumping power. The acceptable bit error rate (BER) and signal quality results prove the feasibility of proposed PP-EDFA for applications in broadband DWDM transmission systems. The PP-EDFA can achieve a maximum transmission distance of 90 km for 95-channel DWDM transmission system.
