The copropagation of two optical pulses of different frequencies in single-mode birefringent fibers is investigated. Various combinations of solitary-wave solutions are obtained. It is shown that a dark pulse on the slow axis and a bright pulse on the fast axis simultaneously propagate without distortion in the presence of a bright pulse of different frequency on the slow or the fast axis.
