Nokia & Islalink achieve 800Gbps over the IONIAN submarine cable
The IONIAN network, launched by Islalink, is a high-capacity submarine system that provides a reliable, future-proof fiber route between Italy and Greece. It connects the two countries through the submarine link and two terrestrial rings, where band C+L is used (9,6 THz), that connect and give redundancy to the main cities in Italy (Milano and Rome) and in Greece (Athens and Thessaloniki). In addition, 1Tbps has been successfully tested in both terrestrial routes of Greece: the south route (452 km), Preveza-Athens, and the north route (975 km), Preveza-Thessaloniki-Athens.
Nokia’s PSE-6s not only enhances network performance but also delivers a 60% reduction in network power consumption per bit, contributing to more sustainable operations. This technology is crucial in supporting data center to data center connectivity, for global tech leaders and other high-demand users.
Esther Garcés, CEO of Islalink, said: “This successful trial proves that the IONIAN network, powered by Nokia’s PSE-6s, is ready to support the next generation of high-speed digital services. Our customers, including tech giants, will benefit from unprecedented capacity, reliability, and efficiency, further enhancing Islalink’s positioning as a key player in the international fiber market.”
Matthieu Bourguignon, Senior Vice President and Head of Europe for Network Infrastructure business at Nokia, said: “This capacity-reach record for unrepeated transmission marks a valuable step forward in optical technology. Nokia’s PSE-6s is designed to provide high-speed, power-efficient connectivity over long unrepeated links like the IONIAN submarine cable. Delivering such capabilities enables Islalink’s delivery of innovative services that unlock new opportunities for their customers in Italy, Greece and Spain.”
