In this paper, we introduced analysis of gain and noise figure of Erbium Doped Fiber Amplifier (EDFA) based on double pass with Wave Selective Coupler (WSC). Main contribution in this study a (WSC) to eliminate the residual pump power out of the signal and attain optimal result in L- band were used. This method decreases the self-saturation effect of ASE. Also show the effect on input and output signal power in L-band Erbium Doped Fiber Amplifiers with pump power using forward pumping. Also analyzed were the high-yield behavior and characterization details of the new double-pass EDFA with WSC. We also show the effects of pump power on gain and noise figure with input and output signal power in L- band at 1590 nm
