SOLITON TRANSMISSION USING PERIODIC DISPERSION COMPENSATION

We examine the behavior of solitons in optical fibers where the disper sion is alternated between the normal and anomalous regimes, The perio dic nature of the system strongly modifies the shape of the stable sol iton (solitary wave) pulses, and increases their energy when compared with solitons in equivalent uniform fibers, Power enhancement factors of up to 70 are numerically observed. This leads to both an increased signal-to-noise ratio (SNR) at the receiver and reduced Gordon-Haus ti ming jitter, The interaction between pairs of isolated pulses is exami ned, We also examine implementations including periodic amplification, and show that the energy scalings introduced by the amplification and the dispersion management are independent provided that the periods o f the two processes are dissimilar. We show that there is an optimum d ispersion compensation ratio which minimizes the received Gordon-Haus jitter, A digrammatic technique is presented for estimating the perfor mance of dispersion compensated soliton transmission systems.
