A Erbium-doped fiber amplifier (EDFA) modulated by a pumping source cause the energy gap of amplified spontaneous emission (ASE) getting the characteristic of modulating signal. The modulated amplified spontaneous emission can be the polarization mode dispersion monitoring system. All the methods we used are based on frequency domain. It is better than the approaches based on time domain, due to the fact that the experimental structure is convenient. The differential group delay (DGD) we calculated by Jones matrix eigenvalue method can be proved by the Poincare’ arc method using Poincare’ arc method. We fixed the polarization state of a tunable laser at 60 degree of linear polarization to incident in EDFA at the range of wavelength 1542nm-1566nm. The data we got from the experiment can be verified the polarization mode dispersion we measured.
