Abstract

Signal distortions in intensity modulated direct detection WDM systems induced by interaction of cross-phase modulation (XPM) and dispersion are investigated experimentally. The results quantify their reduction with increasing channel separation (walkoff) and are in good agreement with simulations. With the chosen setup it is shown that the limiting influence of XPM in standard single-mode fiber (SMF) systems is reduced efficiently for typical channel spacings (/spl ges/0.8 nm).
