We used a two-stages three degrees high-order polarization mode dispersion (PMD) compensating structure. The former stage adopts polarization controller and fixed time-delayed line that is consisted of polarization-maintaining fiber. The second stage adopts a nonlinear chirped fiber grating that is made by hydrogen-doped G652 fiber, which is used to adjust the magnitude of PMD. Use this kind of fiber grating of which the time delay can be adjusted to form the second stage, and then realize the first-order and high-order of PMD compensating on a 40Gb/s OTDM system. The compensator can be used as chromatic dispersion and PMD compensation. The result of experiments revealed that signal’s eye digraph and pulse shape are recovered distinctly.
