Combined Effect of Polarization Mode Dispersion and Chromatic Dispersion on Strongly Filtered pi/2-DPSK and Conventional DPSK
01 June 2004
We find that strongly filtered pi/2-DPSK is better immuned against PMD whereas DPSK has better tolerance towards GVD. Since PMD is more detrimental than GVD, it is more attractive to deploy pi/2-DPSK than DPSK.
