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

Abstract

The purpose 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 the wavelength of 980nm. The performance of this simulation model was evaluated using the parameters Gain, forward output signal power, and ASE noise, and the results were summarized. The results of 2- 16 channels of RZ transmitter and 2- 16 channels of NRZ transmitter were integrated in the simulation model with optical multiplexer and multiplexed signal sent to cascaded Erbium amplifiers with pumping CW (continuous wave) Laser source with wavelength 980nm and Filter. EDFA Gain, output signal power, and ASE noise are correctly represented by the model. The simulation results demonstrate that utilising EDFA and EYCDFA to choose a cautious fibre length of 20m and a pump power of 1mw in single pumping yields ASE noise of 0.005mw and zero milli watts.
