摘要
Numerical simulations concerning the dynamical behavior of infinite and periodic pulse trains, for long distance propagation in single mode optical fibers, are presented. A new optical pulse train configuration that may propagate with high stability in the normal and anomalous dispersion regime in optical fibers is proposed and simulated using the pulse position modulation (PPM) coding. High stability is achieved by simultaneous propagation of two infinite and periodic trains of bright pulses in the normal and anomalous dispersion regime (solitons) in a single mode optical fiber. This configuration could lead to transmission velocities around 300 Gb/s with good stability under PPM coding. (C) 1998 Elsevier Science B.V. All rights reserved.
