We demonstrate how optical pulse trains generated through active mode locking can propagate strictly linearly over many thousands of kilometers of dispersive fiber without significant pulse broadening. The technique relies on the highly coherent modes that constitute a mode-locked pulse. The generated optical pulses are recreated at certain distances given by the fiber dispersion and the pulse repetition rate.
