A reconfigurable optical metro-access network (ROMAN) architecture is proposed in this work with a focus on an innovative reconfigurable optical add-drop multiplexers (ROADMs) based on tunable micro-ring resonators (MRRs). The main aim of this network is sharing bandwidth among different time- and wavelength-division multiplexing passive optical network (TWDM-PON) access trees, linked together by...
The coherent revolution has signalled in a new era for optical networks. Flexible transceivers (TRx) able to adapt a wide range of transport layer parameters such as modulation format, symbol rate, center wavelength, forward error correction (FEC), etc., are the key enabling components that will finally deliver on the promise of dynamic network operation. With flexibility comes the potential for a...
This paper gives an overview on how Software Defined Networking (SDN) principles can be applied to existing optical networks, considering the requirements introduced by the last technology's improvement. A description of a proof of concept activity will be proposed. The demonstration shows how extending SDN to the metro area and wide area network (Transport SDN) can fully exploit the dynamism of an...
