| Abstract |
| The explosive growth of data, particularly internet traffic, has led to a dramatic increase in demand for transmission bandwidth imposing an immediate requirement for broadband networks. Currently core networks widely employ WDM to offer high capacity and long reach transmission capabilities. WDM has recently started becoming a very attractive technology also for metropolitan area networks where the major requirement is cost-efficiency. A real catalyst motivating the use of WDM in MANs is its promise of transparency offering elimination of opto-electronic regenerations. In both network segments the use of transparent solutions introduces impairments penalizing the system performance. These impairments can be significantly suppressed using purposely designed and optimized systems incorporating advanced modulation formats and equalization techniques that assure that the signal performance remains adequate under worst case conditions. The OPTRONET consortium proposes work that will result in the development of such systems and will enable the deployment of cost- and performance- optimized transparent optical metropolitan networks.The partners of the project will design, evaluate, develop and demonstrate novel metro-specific transceiver prototypes. A variety of modulation formats offering great potential for optimized metro networks will be the focus of the project. The option of electronic channel equalization and the performance improvement that it offers will be studied in detail. The different systems will be assessed for technical and manufacturing feasibility, improved system/network performance and customer value. Effort will be assigned in low cost solutions tailored to metro requirements. Simulations will analyze the performance of the systems in a reference WDM metro network, and will determine the optimum implementations for the variety of modulation formats and equalization techniques. Consequently novel transmitters based on advanced modulation formats and receivers offering dynamic signal equalization will be designed and fabricated. The developed systems will be evaluated in laboratory test-beds. In order to verify the proposed solutions a field trial will be performed using real metropolitan networks delivering different types of high-bandwidth services to end-users. The aim of the project is to provide guidelines on technology choices, to define the requirements for optical interfaces and develop advanced transceiver systems in order to meet user as well as operator requirements towards broadband metropolitan topologies. |
