Understood. I’ll get started.
Nokia, in partnership with Islalink, has set a new benchmark in optical technology by achieving an 800Gbps data transmission rate on the IONIAN subsea cable system. Spanning 330 kilometers and connecting Crotone, Italy, to Preveza, Greece, the trial underscores the transformative capabilities of Nokia’s sixth-generation Photonic Service Engines (PSE-6s). This success marks a critical advancement in high-speed data transfer for Europe’s burgeoning digital economy.
The IONIAN cable system, developed to enhance connectivity between Western Europe and the Balkans, leverages the latest submarine optical fiber technology. The trial employed dual C-band and L-band wavelength systems, demonstrating the ability to maintain ultra-high-speed transmissions while significantly reducing power consumption per bit by 60%, a major leap toward sustainable digital infrastructure.
Beyond the subsea link, the trial also included terrestrial segments in Greece, with the PSE-6s delivering up to 1Tbps over the 452-kilometer route from Preveza to Athens and the extended 975-kilometer northern route to Thessaloniki. These achievements reflect the system’s adaptability to diverse network environments, ensuring robust performance across both submarine and terrestrial routes.
Islalink emphasized the importance of this milestone for regional connectivity, noting that the IONIAN system is now poised to support next-generation digital services in Italy, Greece, and beyond. This accomplishment also positions the IONIAN network as a critical player in meeting the growing demand for secure and high-speed data transmission by major tech firms and cloud providers.
Nokia’s PSE-6s technology has drawn industry attention for its ability to drive high-capacity networks while cutting operational costs and environmental impact. This innovation aligns with broader efforts to enhance data center interconnectivity and improve network efficiency for global service providers. By integrating advanced signal processing and spectral shaping techniques, the technology ensures that network operators can push the boundaries of existing infrastructure without compromising reliability or sustainability.
The successful deployment of 800Gbps channels on the IONIAN subsea cable demonstrates the readiness of European digital infrastructure to cater to future demands. As industries increasingly adopt cloud-based operations and data-heavy applications, the need for such high-capacity systems is more critical than ever. The collaboration between Nokia and Islalink highlights the role of private-public partnerships in driving technological advancements and building resilient connectivity ecosystems.
