Abstract
Previous investigations have revealed that the impairments of the
cross-phase modulation (XPM) in dense wavelength-division multiplexing
(DWDM) systems include two aspects: the XPM-induced phase noise and the
XPM-induced polarization scattering. Such XPM phenomena are strongly
dependent on the transmission system configurations and are nonintuitive. In
this paper, a simple fiber model is proposed to facilitate the determination
of XPM effects. By employing this model, the phase noise and polarization
scattering are calculated based on the system configurations and the
time-consuming computation by the split step Fourier method is avoided. The
proposed model is verified by the dual polarization quadrature phase-shift
keying coherent DWDM experiments and simulations in terms of the variance
and autocorrelations of phase noise and polarization crosstalk as well as
their dependence on relative polarization states and the overall Q-impairment. The proposed model helps
deeper analysis of XPM phenomena, and eventually, leads to development of
various XPM mitigation methods through transmission system design and
coherent receiver DSP.
