Abstract
A regenerator is an important element in the long-haul fiber- communication systems. It must provide the conservation of the contrast between the pulses corresponding to logic ones and pulses corresponding to logic zeros; high enough level of the logic ones; and restoration of the pulses position in the sequence. To solve these problems a nonlinear element has to be used. Optical elements based on the nonlinear phenomena in fibers are preferable because of their high pulse repetition frequency operation. Recently elements based on the nonlinear interaction of solitons have been demonstrated.1,2
