Abstract

In this study, the fuzzy logic (FL)-based automatic gain controller (AGC) is designed to obtain a fixed gain level of erbium-doped fiber amplifiers along C band based on experimental results. A FL-AGC with two inputs and one output is considered where the inputs are signal power and signal wavelength and the output is the pump laser current. The output gain variations are examined by varying both input signal levels from -15 to -35 dBm and signal wavelength from 1526 to 1564 nM. The results are well kept within 30-dB gain level with a ripple of +/- 0.1 by using FL-AGC circuit. (C) 2011 Wiley Periodicals, Inc.
