Executive Summary

CROSS Phase Modulation (XPM) is known as the phenomenon that the variations of intensity of one optical signal can change the refractive index of the fiber (Kerr effects), and modulate the phase of other optical signals co-propagating in the same fiber. The authors compare the impact of Q-factor, BER and timing jitter due to CROSS-Phase Modulation (XPM) in a wavelength-division multiplexed system for different length of fiber. They then examine the commonly used method of estimating XPM system penalties from the amplitude of XPM-induced intensity modulation of a Continuous-Wave (CW) probe.
