By introducing an amplified spontaneous emission source as additional noise, two sets of experimental schemes are designed to measure noise figure characteristics of Erbium-Doped Fiber Amplifier employed in an analog optical system. The impacts of the signal power and the Signal to Noise Ratio on the Noise Figure are systematically measured. The qualitative conclusions are obtained that the decline of the input optical power and improvement of signal to noise ratio will lead a rising Noise Figure of Erbium-Doped Fiber Amplifier. These results will benefits the optimization of the analog optical amplifier by providing the proper working conditions of the Erbium-Doped Fiber Amplifier.
