Iterative estimation and simulation analysis of the amplifying sections in optical communication network

Optical WDM networks use high-speed optical trunk lines as backbone network. The maximum number of amplifying sections in the optical line is causally related to power budget, dispersive expansion of code pulses and nonlinear distortions. All parameters are closely correlated. Total signal losses are estimated and through series of iterations a solution is found which for a given number of amplifying sections for the current iteration will yield minimum relative percentage error. A simulation model is developed to validate the proposed approach.
