摘　　要：Starting from our definition of apodization profile functions,we discover the optimal profiles and the characteristics of defined apodization functions in sidelobe suppression.It is shown by numerical analysis that the optimal grating length is 45 mm to compensate for dispersion induced by 100 km fibres and the smoothness of the ripples in time-delay characteristics is related to the defined parameters.
