Recent results on optical access networks from the PRIN project ROAD-NGN

The paper describes the recent results of the Italian National PRIN Research Project ROAD-NGN (Optical frequency/wavelength division multiple access technique for next generation networks) regarding innovative technological solutions able to achieve a significant simplification compared to the NG-PON2 TWDM approach, but increasing both the aggregated transmitted throughput and the data rate available for each user. Downlink and uplink solutions are shown and discussed.
