Abstract: It has been proved that the length of fiber has great contribution to the performance of the 1 550 nm ASE ( Amplified Spontaneous Emission) source, both on the output power and spectral width.To improve the per-formance of the source, a series of experiments is designed, and the result shows that a proper length of fiber can improve the performance of the source.Under normal temperature, we analyze the connection between the length of EDF and output power, center wavelength and spectral width of the ASE source.Finally we derive curve of the ASE source output power and center wavelength under the different EDF length, due to the change of pumping source. The results show that when the fiber is 22 m, the performance of the ASE source is the best.
