Abstract： The use of α-power chirped fiber Bragg gratings for dispersion Cancellation in an optical fiber link is discussed. Numerical and theoretical investigation of recompressing the dispersion-broadened pulse by using α-power chirped gratings is made, which shows that, the dispersion-broadened Gaussian pulse after l00km standard fiber (with zero dispersion at λ= 1.3μm) trnasmission at λ= 1.55μm with initial width of TFWHM = 33ps (full width at half maximum) can be perfectly recompressed with the peak reflectivity of 82% by using a 30mm long α-power chirped fiber grating with proper α value and optimal grating parameters.
