Gain and Noise Figure Analysis of Erbium Doped Fiber Amplifier Based on Double Pass Configuration Using Forward Pumping

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.

Characteristics Analysis of Hybrid Optical Amplifier with Doped Fiber Variations for Fiber Optic Communications Network

“…The desired NF value on different doping is nearly zero. It corresponds to the fact that the lower the NF value, the less noise of the amplified signal [32]. When using Er-doped fiber, the most significant NF occurs at a wavelength of 1530 nm of 15,319 dB and then decreases as the source wavelength increases until it reaches the same as the several variations of doped fiber described earlier.…”
