Recently, Nokia and Islalink successfully tested Nokia’s sixth generation Photon Service Engine (PSE-6s) on a 330 kilometer submarine cable connecting Crotone, Italy and Preveza, Greece, achieving an important milestone.
This on-site test represents a new capacity record for the IONIAN fiber optic cable system’s 800Gbps transmission, demonstrating the capacity and performance of Nokia PSE-6s technology.
The Ionian Network launched by Islalink is a high-capacity underwater system that provides reliable, future oriented fiber optic lines between Italy and Greece. It connects the two countries through an undersea link and two ground loops, using the band C+L (9,6 terahertz), connecting and providing redundancy to major cities in Italy (Milan and Rome) and Greece (Athens and Thessaloniki). In addition, 1Tbps has been successfully tested on two land routes in Greece: the southern route (452 kilometers), Preveza Athens, and the northern route (975 kilometers), Preveza Thessaloniki Athens.
The Nokia PSE-6s not only improves network performance, but also reduces network power consumption by 60% per bit, helping to achieve more sustainable operations. This technology is crucial for supporting data center to data center connectivity for global technology leaders and other high demand users.
Esther Garcsamus, CEO of Islalink, said, “This successful trial proves that the IONIAN network driven by Nokia 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 position as a key player in the international fiber optic market.”
Matthieu Bourguignon, Senior Vice President and Head of European Network Infrastructure Business at Nokia, said, “The record breaking capacity of this non repeating transmission marks a valuable step forward for optical technology. The Nokia PSE-6s is designed to provide high-speed, energy-efficient connectivity on long, non repeating links like the Ionian submarine cable. With these capabilities, Islalink can provide innovative services and bring new opportunities to customers in Italy, Greece, and Spain.”
