| Abstract: | A high accuracy method for measuring polarization mode distribution in single mode fiber is designed, which conquers the weakness of classic method measuring the fiber and fibe component. This system, using short coherent length such as SLD, is of the accuracy of couple intensity up to -80 dB and the resolution of survey distance is 10 mm. A result of measuring Lyot fiber depolarizer is given in this paper. |
