Nokia and Islalink Achieve 800Gbps Capacity-Reach Record over the IONIAN Submarine Cable
Nokia and Islalink Press Release
November 13, 2024
Espoo, Finland – Nokia and Islalink have achieved a significant milestone by successfully testing Nokia's sixth-generation Photonic Service Engine (PSE-6s) over an unrepeated 330km submarine cable connecting Crotone, Italy, with Preveza, Greece.
This field trial represents a new capacity-reach record for 800Gbps transmission over the IONIAN cable system, showcasing the capacity and performance of Nokia's PSE-6s technology.
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), connecting and giving redundancy to the main cities in Italy (Milano and Rome) and Greece (Athens and Thessaloniki). Additionally, 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 enhances network performance while delivering 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 Nokia’s Network Infrastructure business, added:
“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.”
