| 摘 要： | The cascaded chirp fiber Bragg gratings（CFBGs） with ITU-T standard wavelengths and wavelength grid are applied to compensate the dispersion of 8×10 Gb/s WDM system. The ASE of the EDFA could be reduced, the OSNR of the transmitted signal can be increased and the fluctuation of the EDFA gain can be restrained in a certain scope by the CFBG employed in the system. Experiment of error-free 8×10 Gb/s 2015 km transmission without FEC and electric regeneration is demonstrated in this paper. In this system, only EDFA is used as amplifier,and no other form of dispersion compensator is adopted except CFBG. The experimental result showed that after 2 015 km transmission,the consistency of the dispersion compensating for each channel is perfect.

| Abstract: | The cascaded chirp fiber Bragg gratings (CFBGs) with ITU-T standard wavelengths and wavelength grid are applied to compensate
the dispersion of 8×10 Gb/s WDM system. The ASE of the EDFA could be reduced, the OSNR of the transmitted signal can be increased
and the fluctuation of the EDFA gain can be restrained in a certain scope by the CFBG employed in the system. Experiment of
error-free 8×10 Gb/s 2015 km transmission without FEC and electric regeneration is demonstrated in this paper. In this system,
only EDFA is used as amplifier, and no other form of dispersion compensator is adopted except CFBG. The experimental result
showed that after 2015 km transmission, the consistency of the dispersion compensating for each channel is perfect.
