Nokia and Türk Telekom International smash 800Gbps transmission world record on long-haul commercial network

Nokia and Türk Telekom International smash 800Gbps transmission world record on long-haul commercial network

  • New world record 800Gbps transmission is over 2300km on a terrestrial Conventional and Long (C+L) band WDM network.
  • Türk Telekom International can now scale network capacity as well as support extremely high speeds over even longer distances.
  • Latest generation of high-performance coherent optics offers more efficiency and greener transport.

26 June 2024
Espoo, Finland: Nokia, together with Türk Telekom International (TTI), today announced a new world record using Nokia’s sixth generation of super-coherent Photonic Service Engine (PSE-6s) technology. The real-world field trial took place on a highly loaded commercial network over 2300km and achieved an 800Gbps single wavelength international transmission with no regeneration on C+L band WDM infrastructure.

The two companies also conducted real-world demonstrations on similarly highly-loaded links delivering 700Gbps single wavelength transmission over 2500km and 600Gbps over 4100km. They were performed with no regeneration and with traffic loads near 95% of the maximum WDM capacity of the network, further highlighting the scale and performance of Nokia’s optical network solutions.

With these results, the field trial successfully achieved its main target of avoiding regeneration on routes between Turkey and Frankfurt with significantly higher line rates than 200Gbps and 300Gbps that are used today, enabling Türk Telekom International to efficiently scale the bandwidth of its existing network.

Nokia’s PSE-6s enables more sustainable networks with better power efficiency. Leveraging the latest 5-nm DSP silicon integrated circuits and tightly integrated with silicon photonics, the PSE-6s reduces power-per-bit by 40% versus today’s coherent solutions, enabling operators a more attractive Total Cost of Ownership whilst offering greener solutions to their customers.

Zekeriya Erkan, Chief Technology Officer at TTI, said: “Our main target was to avoid regeneration between Turkey and Frankfurt with highly efficient lambdas for transporting aggregated 100GE and 400GE services. We were pleased to validate that the capabilities of the PSE-6S-based transponder on our existing C+L infrastructure allowed us to go beyond our goal and grow the wavelengths from 200/300Gbps to 600/700/800Gbps, thus scaling the overall bandwidth on a brownfield network. These are truly groundbreaking results that will allow us to offer more efficient services, reduced cost and greener transport to our customers.”

James Watt, Senior Vice President and General Manager of Optical at Nokia, said: “Faster, greener, more efficient.  This new industry benchmark of 800Gbps over 2,300 kilometers ticks all the boxes for organizations needing to transmit data at immense scale, over long distances, fast and with the minimum energy use.  In Türk Telekom, we have a partner who is ready to set the bar extremely high and help us push the limits of optical technology.  It’s gratifying to reach this important milestone together.”
