Simulation of autosoliton optical pulses in high-speed fibreoptic communication systems

The propagation of a pulse in a fibreoptic communication link with periodically included regenerators – nonlinear optical loop mirrors, is studied. The autosoliton propagation regime of the optical pulse is revealed. It is shown that the inclusion of a ring mirror to the communication link leads to a substantial increase in the transmission distance of the pulse at a small negative average dispersion in the link.
