Abstract
In this study, we present theoretical and experimental uncertainty analysis of erbium-doped fiber (EDF) characterization to improve performance prediction of erbium-doped fiber amplifiers (EDFAs) in the extended L-band. Through this uncertainty analysis, the optimal EDF lengths for absorption coefficient and emission coefficient characterization are determined to improve precision with a limited number of experimental steps. The uncertainty in the measured clustering ratio is also evaluated based on the uncertainty analysis of absorption and emission coefficients. To verify the accuracy of the Giles parameters determined from the EDF characterization, we compare simulation results, with calculated upper and lower uncertainties for the gain and noise figure (NF), to experimental measurements. The results show that the measured spectral gain and NF match well with the calculated value.
