Abstract :
Recently, long-haul transmission experiments of more than 100-Gbit/s capacity were reported. Wavelength-division multiplexing (WDM) is a key technology to achieve this kind of high-capacity transmission. One technical problem of the long distance WDM transmission is the dispersion slope of the transmission fiber. It causes the difference of the chromatic dispersion accumulation upon the WDM channels, and it will lead to transmission performance degradation. In order to solve the problem, equalization of the dispersion slope should be quite effective. This paper describes the results of the long-distance transmission experiments using the dispersion slope equalization. Both IM-DD WDM and optical soliton WDM are discussed
