Abstract:
    This invention relates to a measurement method for fiber polarization mode dispersion(PMD) under the zero strain state, which winds fibers to a test disk with the radius greater than or equal to 140mm from a small disk in the strain of 0-0.1N, and the fiber length winded on the disk for testing is 0.8-4.2km, the creel of the fiber on the disk is not over 6 rows, then the winded fiber is placed for over 40 min horizontally then is undergone the PMD test, which eliminates the influence of outside stress to PMD and gets more accurate PMD data.
