A1 Austria, Nokia deliver 800Gbps service transmission

April 23, 2024

Nokia and A1 Austria have successfully delivered an 800Gbps service using a single wavelength, covering a distance of 1276km in a live network from Frankfurt to Budapest. The field trial was completed using Nokia’s FP5 network processor silicon and its sixth-generation super-coherent Photonic Service Engine optics (PSE-6s). This achievement marks A1’s first demonstration of an 800Gbps per wavelength over its long-haul network and will help the company meet the increasing demand of its customers.

A1 currently operates a continental-wide IP and optical network across Europe using Nokia’s service router portfolio, offering businesses and wholesale services to enterprises, web-scale players, and communication service providers’ end-users. The combination of 800Gbps router interfaces and 800Gbps long-haul optical transport will allow A1 to efficiently scale its IP service and network capacity and provide wholesale service connectivity to a wide range of business and wholesale customers.

Nokia’s PSE-6s optics were deployed in the shipping DMAT6 transponder with 2.4Tbps capacity, enabling transport of multiple 800GE services while reducing network power per bit. In addition, the FP5 network processor silicon will increase IP peering performance and scales to 800GE ports, reducing power per bit with more efficient IP connectivity and fewer network links. Nokia’s FP5 chipsets boost the networks to run up to 50 Tbps and significantly reduce A1’s operational and hardware costs.

Alexander Stock, CTO at A1 Austria, said: “We are committed to investing in our digital infrastructure and driving digitalisation across Europe, and the success of this trial is a testament to the hard work delivered by our teams and by our trusted partner – Nokia. It’s a remarkable achievement that will not only allow us to lower costs per bit but will also provide the much-needed high-speed connectivity to our wholesale customers in 2024 and beyond.”

Matthieu Bourguignon, Senior Vice-President and Head of Europe, Network Infrastructure at Nokia, added: “This is a great showcase of Nokia’s capability to scale network performance and power efficiency with our chipsets FP5 and PSE-6s. Our IP and Optics solution enables wholesale services providers to support new 800Gbps services for end-users with the lowest network cost and power per bit, over any distance, including long-haul links, and we are proud A1 selected Nokia to reach this achievement.”

During the field trial, Nokia’s 7750 SR-1-46S router with FP5 supporting 800Gbps ports was connected to Nokia’s 1830 PSI-M with a PSE-6s line card operating at 800Gbps per wavelength over a 32-degree ROADM/WDM line system across 16 spans and 3 ROADM nodes.
