Abstract

A novel architecture of Phase-Modulated Duobinary (PM-Duobinary) modulation format is proposed in this study. It is an enhanced modulation scheme to the conventional Duobinary modulation format. The proposed hybrid PM-Duobinary is an external modulation format, where the modulators are needed for the generation of the optical signal for transmission. In this paper, the performance comparison among PM-Duobinary modulation format, conventional Duobinary modulation format, and non-return-to-zero on-off keying (NRZ-OOK) modulation format is also investigated. The obtained results show that, the PM-Duobinary modulation format can significantly improve the transmission distance by 44.4% and 80.5% over the conventional Duobinary and the NRZ-OOK modulation format, respectively..
