Nokia and Vodafone Turkey achieve maximum optical transmission capacity

Nokia has announced it has broken new ground with Vodafone Turkey with a regional demonstration of a 1Tb / s ( terabit per second ) per channel coherent transmission over its live optical network . The companies proved a capacity increase of 150 % over a single channel coherent transmission and the ability to scale network capacity up to 70Tb / s per fibre . This capacity milestone is part of an on-going modernisation effort with Nokia to futureproof Vodafone Turkey ’ s optical architecture .

Increasing the speed of its optical network is key to providing maximum capacity for the ever-increasing data demands of Vodafone Turkey ’ s customers . 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 .
The optical test showcased 1Tb / s capacity over 130 GHz bandwidth without any errors on Vodafone Turkey ’ s live optical network between its data centres . The trial was conducted over the operator ’ s in-service optical network , based on Nokia ’ s leadingedge wavelength routing technology , which includes its high performance , 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 .
Also used was 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 , optimised for data centre 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 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 , 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 modernise Vodafone Turkey ’ s optical network . Together , we are accelerating their Digital Transformation with solutions that can be easily scaled to meet 5G demands .” p
