Performance Comparison of alCNRZ and nCRZ Modulation Format for WDM/DWDM System
Journal Title: International Journal of Advanced Research in Computer Engineering & Technology(IJARCET) - Year 2013, Vol 2, Issue 7
Abstract
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 higherorder dispersion compensation and phase modulation. The performance of alCNRZ and nCRZ has been analytically compared on various values of phase modulation and higherorder dispersion term to find out which modulation format is better in this regard.
