Statistical analysis of crosstalk accumulation in WDM networks

Accumulation of inband crosstalk in all-optical networks is studied. By app lying statistical methods, we have investigated how inband crosstalk accumu lation influences the performance of optical networks of different configur ations. Our study shows that there exists a delicate dependence between net work topology and robustness with respect to accumulation of inband crossta lk, A method is proposed to design optical networks with optical paths sati sfying a certain level of inband crosstalk performance.
