Abstract

Recently, Information Superhighway becomes an attracting subject, so does in telecommunication area. Having incomparable characters in high speed transmission system, Soliton transmission system will be more competent for being the dominate transmission medium in Information Superhighway. After the soliton controlling technique had been utilized in the soliton system by introducing the filters or the modulators behind each amplifier, the well known Gordon-Haus effect,¹ which hinders the improvement of the system capacity, had been reduced considerably. The time fluctuation led by the amplified spontaneous noises will no longer be the obstruction in the soliton transmission. But, world never develop as expected. The inserting of filters or modulators to suppress the time fluctuation introduced an excess gain, which compensated for the loss due to the limit bandwidth. Thus, the excess gain resulted in an extremely large amplitude fluctuation, especially in the high speed system. Several research² had focused on this subject. For our knowledge, the complete mathematical model for the amplitude fluctuation, or for energy jitters, has not yet been given.
