Nokia says it has completed a successful 600-Gbps transmission trial with Italy’s TIM. The trial included the transmission of 600 Gbps over a 1008-km link within TIM’s terrestrial fiber backbone network.The trial used fielded colorless, directionless, and directionless flexible-grid ROADMs from Nokia (specifically, 1830 PSI-M compact modular disaggregated transport systems) that TIM is using for its backbone infrastructure. The ROADMs were equipped with the technology vendor’s PSE-Vs super coherent optics. The 600G transmission leverage 100-GHz channels and produced a spectral efficiency of 6 ...
