Impact of the fiber type and dispersion management on the performance of an NRZ 16 /spl times/ 40 Gb/s DWDM transmission system

We examine the impact of the fiber type and dispersion management on the performance of a 16 /spl times/ 40 Gb/s dense wavelength-division-multiplexing nonreturn-to-zero transmission system. The transmission line is composed of G.652 or G.655 fiber with periodic dispersion compensation and hybrid Raman erbium-doped fiber amplifier amplification.
