This paper reports on the overall outcome of the FP7 DISCUS project, which aimed at designing end to end architectures, protocols and a physical layer exploiting Long-Reach Passive Optical Network an integrated access and metro network interconnected with a low cost flat optical core network. Our architectural modelling results show that the benefits of node consolidation on the access side extends...
This paper reports on the architectural, protocol, physical layer, and integrated testbed demonstrations carried out by the DISCUS FP7 consortium in the area of access–metro network convergence. Our architecture modeling results show the vast potential for cost and power savings that node consolidation can bring. The architecture, however, also recognizes the limits of long-reach transmission for...
Within the scope of our EU FP7 C3PO project, we are developing novel, energy-efficient, colourless photonic technologies for low-cost, next-generation dense wavelength-division-multiplexed metro transport and access networks. The colourless transmitters use reflective arrayed photonic integrated circuits, particularly hybrid reflective electroabsorption modulators, and multi-wavelength laser sources,...
We present recent efforts for developing “greener” and future-proofed communication networks by employing reflective architectures in the metro edge and access parts of the network. Colourless and coolerless reflective photonic integrated circuits are used in combination with high port-count optical switches for creating costeffective, scalable and dynamic network architectures, delivering 100 Gb/s...
We report progress towards low-power, colourless reflective photonic integrated circuits for cost-effective DWDM 100 Gb/s metro transport and 10 Gb/s access networks within the EU FP7 C3PO project.
