Abstract
In this paper, gain and noise figure of Erbium Doped Fiber Amplifier (EDFA) is analyzed based on double pass with Wave Selective Coupler (WSC). The main contribution in this study the use of a (WSC) to eliminate the residual pump power out of the signal and attain optimal result in L-band. This method decreases the self-saturation effect of ASE. Also, the study shows the effect on input and output signal power in L-band Erbium Doped Fiber Amplifiers with pump power using forward pumping. Moreover, the researchers analyzed the high-yield behavior and characterization details of the new double-pass EDFA with WSC. Finally, the study shows the effects of pump power on gain and noise figure with input and output signal power in L-band at 1590 nm.
