Features of wave packet dynamics in linear and nonlinear optical fibers are studied allowing for complex-valued dispersion parameters. It is shown that the presence of imaginary components in dispersion parameters affects considerably the compression behavior of a wave packet in single-element and cascaded optical fibers; causes a shift in carrier frequency; and creates frequency-modulated wave packets with a superluminal envelope maximum.
