We introduce the concept of ''breathing'' solitons to describe the dynamics of optical pulses in transmission lines with passive compensation of fiber chromatic dispersion. The ''breathing'' pulse can be used as the information carrier. The theory presented is complimentary to the concept of the guiding-center soliton. It is shown that an average bright soliton can propagate in a system with large variations of the dispersion, including segments with high normal dispersion. (C) 1996 American Institute of Physics.
