    Sliceable bandwidth-variable transponders (SBVTs) enable the adaptation of transmission parameters according to traffic requirements and network constraints. In this study, SBVTs capabilities are evaluated in the context ...
  • On the benefits of differentiating the filter configurations in flexi-grid optical networks 

    Castro Casales, Alberto; Cugini, Filippo; Velasco Esteban, Luis Domingo; Castoldi, Piero (Institute of Electrical and Electronics Engineers (IEEE), 2014)
    Conference report
