Analysis of ASE NOISE Using the Simulation Model EDFA – Cascaded with EYCDFA


The goal of this paper is to investigate the noise power of ASE (Amplified Spontaneous Emission) using the simulation model EDFA (Erbium Doped Fiber Amplifier) cascaded with EYCDFA (erbium-ytterbium co-doped fibre amplifier) in 4-16 channels of transmitters combined by optical multiplexer and sent the output to EDFA in series with EYCDFA in single backward pumping using 980nm wavelength. The Gain, forward output signal power, and ASE noise parameters were used to evaluate the simulation model’s performance, and the findings were summarised. The simulation model with optical multiplexer and multiplexed signal supplied to cascaded Erbium amplifiers with pumping CW (continuous wave) Laser source with wavelength 980nm and Filter included the results of 2- 16 channels of RZ transmitter and 2- 16 channels of NRZ transmitter. The model accurately represents EDFA Gain, output signal power, and ASE noise. The simulation results show that using EDFA and EYCDFA to select a conservative fibre length of 20m and a pump power of 1mw in single pumping leads in ASE noise of 0.005mw and zero milli watts.
