All Optical Network Dimensioning Considering Transmission Impairments and Mitigation using Electronic Equalization

Abstract:
For a given physical network, in the design and planning, transmission technology selection and network optimisation are carried out such that the network is designed and dimensioned to meet the given traffic demand. Two aspects are important: sufficient transmission performance and optimised cost. In this paper, we consider an all optical network, looking into the static routing and wavelength assignment incorporating the physical transmission, , with an objective to assign a wavelength path to each demand and place the amplifiers and dispersion compensation suitably in the network to achieve physical feasibility of the light paths and a cost effective network. Simplified transmission rules were given to allow fast computation and verification of the light paths used in the RWA. Electronic equalisation using MLSE is considered in the network to compensate transmission impairments, its benefit in reducing the in-line dispersion compensation and associated amplifiers of a metro network scenario is quantified. We also show the cost benefit of an all optical implementation over the opaque network.
