摘要：Advance Modulation formats like alternate chirped non-return-to-zero (alCNRZ) and novel chirped return-to-zero (nCRZ) are playing a significant role in transmission of an optical signal accurately at its destination. High-speed optical signal transmission over long distance is usually achieved by alCNRZ with enhanced nonlinear tolerance. On the other hand increased spectral efficiency and narrower signal spectrum is obtained through nCRZ. In this paper, the comparison between alCNRZ and nCRZ is made on the basis of their performance in presence of higher- order dispersion compensation and phase modulation. The performance of alCNRZ and nCRZ has been analytically compared on various values of phase modulation and higher- order dispersion term to find out which modulation format is better in this regard.
