Review and comparative assessment of FDMA-PON vs. TDMA-PON for next-generation optical access networks

We present in this paper a comparative assessment of Time Division Multiple Access Passive Optical Networks (TDMA-PON) and Frequency-Division Multiple Access Passive Optical Networks (FDMA-PON). We try to point out the pros and cons of the two different approaches in the context of very high capacity next-generation PON mainly in terms of physical layer transmission performances, but also introducing some comparison in terms of complexity, cost and power consumption

Next generation passive optical networks using frequency division multiplexing

We discuss the use of frequency division multiplexing in next-generation PON. We start by discussing pros and cons of FDMA compared to traditional TDMA approach, then present the latest results from the EU project FABULOUS

Lo stato della banda larga in Italia: opportunità, ostacoli, tendenze

Sommario - Questo articolo intende riportare brevemente sul simposio intitolato “Sviluppo dell’ultra-broadband in Italia” tenutosi a Torino nell’ambito di Fotonica 2015, convegno italiano di riferimento per le tecnologie ottiche, in maggio. Sarà inoltre analizzato lo stato di definizione delle reti ottiche di accesso di nuova generazione, con un’accenno alle tendenze per le tecnologie non cablate, nell’ottica delle reti convergent

Remotized Control of Power Electronic Devices Exploiting a Plastic Optical Fiber Photonic Bus

The Internet of Things paradigm and the ubiquitous diffusion of Power Electronic Converters in many fields of application are suggesting the possibility of new ICT services associated to advanced power conversion. This work investigates the feasibility of shared centralized control and communications units able to control and synchronize different power converters, enabling real-time control and telemetry with a cloud approach on the Internet. Our research is focused on defining a proper communication bus making communications between devices and their remote control and telemetry possible in such a challenging environment
