Nokia and OTE Group set dual world-record optical transmission rates over ultra long distances

Nokia together with OTE Group, a member of Deutsche Telekom (DT), today announced two new optical transmission rate world records using Nokia’s sixth generation of super-coherent Photonic Service Engine (PSE-6s) technology. The field trial, which used Nokia’s 1830 PSI-M optical transport solution, ran over OTE Group’s national dense wavelength division multiplexing (DWDM) network, connecting IP Core data centers and routers in Greece. Two optical nodes were installed in Patra and Athens to boost performance over the specific fiber optic routes using PSE-6s coherent optics. As a result, Nokia and OTE achieved record-breaking speeds in a live network in real conditions, transmitting 800Gbps on a single channel over 2580 km, and 900Gbps over 1290 km. This was achieved over a DWDM link transmitting a full load of DWDM channels over 4.8THz of spectrum and supported a total network capacity of 25.6 Tbps per fiber. The companies also demonstrated 1.2 Tbps transmission on a single channel over 255 km. Running an optical solution with Nokia’s PSE-6s allows the increase of network capacity and spectrum utilization, reduces energy consumption per bit by 40%, and minimizes the network's carbon footprint.
