Fiber Bragg gratings with phase-only sampling has been shown to greatly increase the reflectivity of multi-channel designs when compared to equivalent amplitude sampling. A new 21 channel grating design that exhibits excellent channel to channel uniformity is presented in this paper. When used as a dispersion compensator it cancels the chromatic dispersion of an 80 km long section of standard telecommunication fiber (SMF-28) in the 40GBd data link. The individual channels are separted by 200 GHz, thus covering the whole C-band.
