Higher Speed PON

Tutorial - We.C.1.T Towards More and More DSP in Higher Speed PON Access Networks

Roberto Gaudino Politecnico di Torino

This Tutorial will present the recent evolutions towards the definition of next-generation physical layer for PON. International standardization bodies (IEEE and ITU-T) are currently considering different options when focusing on 100G-PON or 200G-PON. In both cases, digital signal processing (DSP) will increasingly be needed in the OLT and ONU transceivers. This Tutorial will review the possible options in terms of modulation formats and DSP technologies in relation with the available high-bandwidth optoelectronics. A key point that will be analyzed are the PROs and CONs of IM-DD (which will likely be the choice for 100G-PON) and coherent (for 200G-PON).

Speaker Biography Roberto Gaudino, Ph.D, is Full Professor at Politecnico di Torino, Italy. His current main research interests are in modelling of optical communication systems and in the experimental implementation of optical networks, with specific focus on access networks. In the last years, he focused his activity on next-generation passive optical access networks (PON) and on ultra-high capacity systems for short reach links. Previously, he worked extensively on fiber modelling, optical modulation formats (such as duo-binary, polarization or phase modulation), coherent optical detection, plastic optical fibers and on the experimental demonstration of packet switched optical networks. He is currently the Coordinator of PhotoNext, the Inter-Departmental Center on Applied Photonics at Politecnico di Torino. He is co-author of more than 280 papers in the field of Optical Fiber Transmission and Optical Networks. For further information, please visit www.optcom.polito.it and www.photonext.polito.it.
