Quarter terabit (25/spl times/10 Gb/s) over 9288 km WDM transmission experiment using nonlinear supported RZ pulse in higher order fiber dispersion managed line

We experimentally show that RZ pulse transmission with narrow spectral broadening over a wide wavelength range is possible in higher order dispersion managed fiber spans. WDM transmission with total capacity of 25/spl times/10 Gb/s is also demonstrated.
