Abstract This work presents the realization by simulation a breves generator of pulse has different flow rates (40 GHz, 80 GHz, 160 GHz). In a first step, we have realized the source of short pulse train at 40 GHz by the non-linear compression of a sinusoidal flapping through a process of mixtures four multi-wave, using the Mach-Zehnder modulator and optic isolator simple. In a second step, the pulse train obtained is then fiberized to reduce the duty ratio of 1/5 to 1/16. In a third step the train obtained encoded then multiplexed to a throughput of 80 Gbit/s. In the last step, we present the re-coding and re-multiplexing again, in order to obtain a rate of 160 Gbit/s, in order to perform simulation a brief pulse generator, simple, easy implementation, is not expensive, in three outputs of different rates, stable and without jigs.
