Abstract
The intensity distortion caused by cross-phase modulation (XPM) limits transmission distances and capacities of high-speed, dense WDM systems. Optimisation of system design can minimise the impact of XPM. Pump-probe experiments are described investigating XPM distortion as a function of typical system parameters for a single fibre link and for multi-span transmission using a fibre recirculating loop. Different dispersion maps and their influence on the XPM generation and phase-to-intensity conversion were investigated. The results are in good agreement with theory and computer simulations. The distortion depends strongly on channel walk-off in the system, increasing for narrow channel spacing and low dispersion.
