This paper describes the impact of novel Return-to-Zero (RZ) formas for dense wavelength-division-multiplexing (DWDM) transport systems using 40-Gbit/s channels. The introduction of phase modulation using phase reversal in RZ-signal encoding process dramatically reduces its optical modulation bandwidth and enhances its tolerance against fiber nonlinearities. By using proposed RZ formats, DWDM transmission performance in 40-Ghit/s channels can be enhanced with high spectral efficiency compared with conventional Non-Return-to-Zero (NRZ) and Return-to-Zero (RZ) formats.
