Abstract :
We numerically study cross-phase modulation (XPM) statistics in 100% precompensated wavelength-division-multiplexing transmission with on-off keying (OOK) and differential phase-shift keying (DPSK) formats. XPM and its randomness are determined by nonlinear diffusion bandwidth and specific modulation format in the target channel. XPM degradation in DPSK channels shows much less stochastic than that in OOK channels. The small duty cycle also helps to reduce XPM randomness.
