Cost-effective Coherent Systems for Metropolitan Networks

Future network services are conceived around the joint use of different heterogeneous resources while combining networking and cloud functions. In order to tackle such a huge challenge, dynamic data plane solutions are needed. In fact, transmission systems need to be agile, programmable, and capable of transmitting large amounts of data dynamically. These transmission systems are expected to be cost/power-effective while covering actual metropolitan networks.In this work, we present transmission solutions using coherent detection combined with either direct or external modulation, with special focus on flexible, high capacity and cost-effective systems. The performance of the proposed technologies is evaluated by experiments and careful numerical modeling.Grant numbers : AURORAS - Autonomic and disaggregated optical networks leveraging edge computing and photonic technologies (RTI2018-099178-B-I00).© 2020 IEEE.
