Long-haul 16 x 10 Gb/s WDM transmission experiment using higher order fiber dispersion management technique

We propose a dispersion management scheme for long-haul wavelength-division-multiplexed (WDM) transmission systems that considers not only second-, but also third-order dispersion using transmission fibers with opposite dispersion signs; it eliminates waveform distortion due to the existence of third-order dispersion with reducing interchannel interaction caused by fiber nonlinearity. With this technique, WDM transmission with a total capacity of 160 Gb/s is demonstrated over 9412 km.
