title: Effect of dispersion on nonlinear phase noise.
abstract: The variance of nonlinear phase noise is analyzed by including the effect of intrachannel cross-phase modulation-induced nonlinear phase noise. Consistent with Ho and Wang [IEEE Photon. Technol. Lett.17, 1426 (2005)] for a lightwave transmission system but contrary to the conclusions of both Kumar [Opt. Lett.30, 3278 (2005)] and Green [Opt. Lett.28, 2455 (2003)] with different initial conditions, the variance of nonlinear phase noise does not decrease much with the increase of chromatic dispersion. The results are consistent with each other after a careful reexamination.
