150% capacity increase demonstrated over single channel

Nokia and Vodafone Turkey have successfully completed a regional demonstration of a 1Tb/s per channel coherent transmission over the latter’s live optical network. 

The companies say that they have proved a capacity increase of 150 per cent over a single channel coherent transmission, and the ability to scale network capacity up to 70Tb/s per fibre. This was as part of an ongoing modernisation effort to future-proof Vodafone Turkey’s optical architecture.

This optical test builds upon an earlier trial conducted by Nokia and Vodafone Turkey that validated a 1Tb/s clear channel IP router interface, further preparing the operator’s network for the future. It showcased 1Tb/s capacity over 130GHz bandwidth without any errors on Vodafone Turkey’s live optical network between its data centere. The trial was conducted over the operator’s in-service optical network, based on Nokia’s leading-edge wavelength routing technology, which includes its CDC-F ROADM optical switch architecture. Supporting operation over C+L bands, Nokia’s optical line system also enables a doubling of the total fiber capacity of Vodafone Turkey’s network.

Also used was Nokia’s photonic service engine (PSE) technology, designed to provide 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, optimised for data centre interconnect applications over metro, regional and long-haul distances.

Thibaud Rerolle, CTO at Vodafone Turkey, said: ‘We are committed to using next generation technology to provide the most convenient services to our customers – uninterrupted and reliably. Our fibre 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 at Nokia, added: ‘We are pleased to complement our deployment of advanced optical transport solutions with the successful and timely completion of this crucial trial to modernise Vodafone Turkey’s optical network. Together, we are accelerating their digital transformation with solutions that can be easily scaled to meet 5G demand.’
