Paper Abstract

Sophistication of the transmission format for 40-Gbit/s/ch WDM networks is indispensable. In long-haul transmission applications, the selection of transmission format should be a principal issue. In this paper, we overview several transmission formats regarding tolerance for fiber nonlinearity, group velocity dispersion, polarization mode dispersion, and spectral efficiency. We address and describe the superior performance against these impairments and high spectral efficiency of carrier-suppressed RZ and its related formats. The special spectrum structure of these formats enables a novel mode-splitting detection scheme. The scheme realizes variety of impact on 40-Gbit/s/ch WDM applications; expansion of dispersion tolerance, automatic dispersion compensation, and BER improvement by adopting a novel frequency diversity receiver.
