Network design parameters such as spectral bandwidth and channel symbol error rate (SER), are analysed. We simulated the transmission of quadrature phase shift-keying (QPSK) signals, modulated at 56 and 100 Gbps, to evaluate a proposed flexible spectral allocation method in order to evaluate the effect of number of channels and the required total spectral bandwidth.engElastic optical networksflexible spectrum allocationoptical channelssignal bandsymbol error rateTrabalho apresentado em evento10.1117/12.2290964Acesso aberto2-s2.0-850495271882-s2.0-85049527188.pdf
