| Abstract: | A new method is proposed to measure the output states of polarization of single mode fiber with a polarizer and an optical spectrum analyzer, the differential group delay (DGD) of polarization mode dispersion (PMD) can be acquired. Comparing with previous methods, this new method saves measure time, and decreases the error come from variation of PMD with time, so it can improve the precision of measuring. |

| Keywords: | polarization mode dispersion principal state of polarization differential group delay Poincaré sphere |
