GCO - Grup de Comunicacions Òptiques Àrees temàtiques de la UPC::Enginyeria de la telecomunicació::Telecomunicació òptica Optical digital twin Network automation Quality of transmission estimation In this work, the outline for a live demonstration of the multiband OCATA digital twin is presented. This digital twin enables intelligent functions such as quality of transmission (QoT) estimation and adaptive model tuning, among other functionalities. This demonstration highlights the integration of deep neural networks (DNNs) to simulate end-to-end multiband lightpaths across C+L+S spectral bands. A live deployment on a virtualized testbed at UPC, Barcelona, showcases the OCATA DT's abilities in two main scenarios. Attendees will engage with an interactive dashboard to explore how the DT estimates QoT and refines its internal models using telemetry data. This demonstration aims to illustrate the practical benefits of digital twins for autonomous network operation, performance assurance, and cost-efficient scaling of next-generation optical infrastructure. The research leading to these results has received funding from the European Union's Horizon Europe research and innovation programme SEASON (G.A. 101096120), The European Commission MSCADN NESTOR (G.A.101119983) and from the ICREA Institution.
