Scalable mobile fronthaul with spatial and spectral reconfigurability through virtually passive nodes
A flexible access and mobile fronthaul architecture with spectral re-allocation capability and dynamic lightpath provisioning among network segments is presented. Fully-passive operation of the optical distribution network (ODN) is retained through reconfigurable optical add-drop multiplexers (ROADM) that are solely supplied by means of energy harvesting at the optical layer with a low feed level of -9 dBm. Deployment with a typical power consumption amounting to 90 fJ/bit guarantees an energy-conscious fronthaul technology. It is further proved that urban radio access networks powered by a software-defined optical fronthaul can reduce the required amount of spectral resources by ~26% during on-peak when migrating to 5G.
