A chirped multiwavelength fiber Bragg grating is developed with the wavelength and wavelength interval in accordance with the ITU T standard. With this multiwavelength chirped grating, the multi-wavelength wavelength can be compensated for dispersion simultaneously. The chirped multiwavelength fiber Bragg grating Can filter out the spontaneous emission noise (ASE) of the amplifier in the unused wavelength range between the reflection peaks, and perform 8 × 10Gb / s 10 2km dispersion compensation experiment, and the channel compensation consistency is good.
