分散マネージメントを用いた光ソリトン伝送

抄録

Optical soliton transmission in a cascaded fiber link is one of the most attractive methods for future optical communications. However, to achieve stable soliton transmission, the amplifier spacing has to be much smaller than the dispersion length, which limits the bit rate for certain amplifier spacing. To overcome this problem, changing dispersion of the fiber in proportion to the local power between the optical amplifiers is effective. This paper introduces the basic idea of the dispersion management in soliton transmission and its application to TDM and WDM soliton transmission.
