The real-time scheduling and routing in dynamic transparent optical networks requires fast and accurate evaluation of transmission penalty caused by nonlinear kerr effects with different dispersion maps. However, the conventional method using nonlinear phase shift can only be applied to assess the nonlinear penalty with optimized dispersion maps. In this paper, we introduce pulse broadening factor...
In this paper we present an approximate analytical formula for root mean square (RMS) pulse width and give a novel approach based on pulse broadening factor to assess the nonlinear transmission characteristics of a fiber-optic communication link. We show that this approach can be applied to predict physical impairment penalties due to nonlinear effects for dynamic transparent optical networks. This...
