Nokia claims a new speed record with Vodafone Turkey with a regional demonstration of a 1 Tbps per channel coherent transmission over a live optical network. The companies proved a capacity increase of 150 percent over a single channel coherent transmission, and the ability to scale network capacity up to 70 Tbps per fiber. This capacity milestone is part of an ongoing modernization effort with Nokia to future-proof Vodafone Turkey’s optical network architecture.
This optical transmission test builds upon an earlier trial conducted by Nokia and Vodafone Turkey that validated a 1Tbps clear channel IP router interface, further preparing the operator’s network for the future.
The optical network speed test showcased 1 Tbps capacity over 130 GHz bandwidth without any errors on Vodafone Turkey’s live optical network between its data centers. The trial was conducted over the operator’s in-service optical network, based on Nokia’s wavelength routing technology, which includes its non-blocking CDC-F ROADM optical switch architecture. Supporting operation over C+L bands, Nokia’s optical line system also enables a doubling of the total fibre capacity of Vodafone Turkey’s network.
Nokia’s photonic service engine (PSE) technology, providing maximum performance and spectral efficiency. The Nokia PSE coherent optics are deployed in Vodafone Turkey’s network using the 1830 PSI-M (Photonic Service Interconnect-Modular) compact modular optical networking platform, optimized for data center interconnect applications over metro, regional and long-haul distances.
Thibaud Rerolle, CTO at Vodafone Turkey, said: “At Vodafone Turkey, we are committed to using next generation technology to provide the most convenient services to our customers – uninterrupted and reliably. Our fiber optic backbone is an important step on the way to 5G and, with Nokia, we continue to equip our optical network with the latest technologies and innovations for our services today and in the future.”
James Watt, Head of Optical Networks Division, Nokia, said: “Our field-proven optical technologies and solutions are enabling service providers like Vodafone Turkey to meet growing capacity demand and provide the best end-user experience. We are pleased to complement our deployment of advanced optical transport solutions with the successful and timely completion of this crucial trial to modernize Vodafone Turkey’s optical network. Together, we are accelerating their digital transformation with solutions that can be easily scaled to meet 5G demands.”
Separately, Nokia today announced that it has been selected to roll out UScellular’s standalone 5G core network with deployment expected to be completed by the end of 2022.
- UScellular will deploy Nokia’s portfolio of hardware, software and services to enable its 5G standalone (SA) core network
- UScellular’s 5G SA network will provide its 5 million customers with superior service, capacity, and reliability
By implementing Nokia’s 5G SA core, UScellular will be able to unlock the full potential of 5G for its customers, delivering the high speeds and low latencies that will power new applications such as virtual and augmented reality. UScellular will also be able to leverage Nokia’s cloud-native, open modular structure to rapidly introduce and scale future network functions for new revenue opportunities.
UScellular’s deployment of Nokia’s 5G core adds to its existing support for the Radio Access Network (RAN) where Nokia is supplying its AirScale radios for both low-band and mmWave 5G.
Mike Irizarry, Executive Vice President and Chief Technology Officer, UScellular:
“As we continue to expand and enhance our 5G network, we value the innovation and support that Nokia provides to help us deliver a superior wireless experience to our residential and business customers. As we deploy 5G SA core, Nokia brings expertise, technology excellence and the right mix of hardware, software and services to meet our requirements for high performance and low latency.”
Ed Cholerton, President of Nokia North America:
“We are thrilled to be selected by UScellular to deliver a full 5G experience to its customers. Our 5G SA core and 5G radios provide not only new capabilities, scale, operational efficiencies, and revenue opportunities, but drive a far better user experience that customers expect. Working with UScellular to provide the core network function software and cloud infrastructure continues our momentum in the North American standalone 5G core market.”
Nokia’s 5G SA core is a cloud-native architecture with network functions deployed as microservices that can be moved to the network edge to meet low latency requirements for software-driven services, like network slicing. Globally, Nokia has already deployed over 250+ cloud core networks and 70+ 5G standalone core networks.
Nokia said its 5G SA core is currently deployed in more than 70 networks globally, but very few of those are commercially available.
Nokia also sold its 5G SA core to T-Mobile US, the first operator to deploy a 5G SA core. It remains the only U.S. operator with a commercially available standalone 5G network.
5G SA cores remain incredibly scarce. Most of the 141 live 5G networks at the end of April 2021 were still operating in non-standalone mode (5G NSA), Stéphane Téral, chief analyst at LightCounting, noted during a panel discussion at MWC Barcelona 2021. As of the end of July, there were only nine standalone networks globally, he said. The latest was KT Corp.’s 5G SA core deployment using Samsung’s technology.
A 5G SA core introduces many unique 5G features, including higher data throughput and performance, lower latency, network slicing. It separates the data and control planes which is required for mobile edge computing and many industrial applications.
