Applications and Research

Cinia Group, a Finland-based designer, builder, and operator of intelligent connectivity and ICT solutions, and Alcatel-Lucent Submarine Networks, now part of Nokia, have successfully completed tests on the C-Lion1 submarine cable system demonstrating a record-breaking capacity of 18 terabits-per-second (Tbit/s) of data per fibre pair. The confirmed rate of 18 Tbit/s per fibre pair, was done using Alcatel-Lucent Submarine Networks’ unique 1620 SOFTNODE 8QAM technology over 8 fibre pairs cable.

Cinia said that achieving a capacity of 144 Tbit/s demonstrates that C-Lion1 can effectively handle increased connectivity and data centre requirements driven by cloud computing, big data and digitalization. Connecting Germany and Finland, C-Lion1 connects data centres in Northern and Central Europe, and offers a low-latency route between Europe and Asia.

The C-Lion1 submarine cable system features the latest generation of ASN high-performance wet plant based on extended repeater bandwidth and new generation of coherent submarine fibre (CSF-2).   ASN’s new 300G 8QAM technology from its 1620 SOFTNODE enables smart spectrum engineering. Additionally, the use of gridless, coherent detection and advanced error correction coding work in combination with non-linear compensation to counteract the signal distortions and noise that impact high speed, long-distance transmission performance.

Taneli Vuorinen, Senior Vice President at Cinia Group, said, “This result demonstrates Cinia’s ability to provide ultra-high speed connectivity services with lowest latency for data centres, enterprises and data intensive organisations. The C-Lion1 implementation project with ASN was successfully completed as planned, and the new connection is now set to fuel the development of the digital economy.”

Vincent Lemaire, Vice-President Technical Operations at Alcatel-Lucent Submarine Networks, said, “This achievement showcased the performance of our open wet plant, which offers carriers a unique adaptive evolution for tuning the system capacity and performance throughout the life of a system. With the recent availability of our 1620 SOFTNODE, the ASN solution provides a distinctive networking model to cope with increasing end-user service demands.”
