Türk Telekom International (TTI) used Nokia’s sixth generation of super-coherent Photonic Service Engine (PSE-6s) technology to transmit an 800 Gbps single wavelength over 2,300 km -- a new distance record according to the companies.
The real-world field trial took place on a highly loaded commercial network with no regeneration on C+L band WDM infrastructure.
The two companies also conducted real-world demonstrations on similarly highly-loaded links delivering 700 Gbps single wavelength transmission over 2500km and 600 Gbps 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.
The companies said the field trial successfully achieved its main target: avoiding regeneration on routes between Turkey and Frankfurt with significantly higher line rates than 200Gbps and 300Gbps that are used today.
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.”
