We study a whole compensation system for chromatic dispersion and polarization mode dispersion, including monitoring subsystems and compensation subsystems in optical communication systems with single channel speed 40Gbit/s and CSRZ format. We employed the spectral shift effect of a semiconductor optical amplifier for chromatic dispersion monitoring, and a non-linearly chirped fiber Bragg grating for chromatic dispersion compensation. The degree of polarization characterizes is used as feedback control signal of polarization mode dispersion monitoring, and a polarization controller and a polarization maintaining fiber are formed a polarization mode dispersion compensator. The transmission experiment demonstrates that the whole compensation system is effective. It is suit for chromatic dispersion management and polarization mode dispersion eliminating in optical communication systems with high single channel speed and CSRZ format.
