We propose a novel approach to combating the pulse broadening effect of group-velocity dispersion in a fiberoptic communication link. In our scheme linear loss in the fiber is balanced by a chain of periodically spaced, phase-sensitive, degenerate optical parametric amplifiers. Analysis of pulse propagation in such a fiber line shows that due to attenuation in the quadrature orthogonal to the amplified quadrature it is possible for a pulse to propagate without significant broadening over lengths much longer than the usual dispersion length of the fiber.
