Nokia's PSE-6s photonic service engine carries 1.2 Tbps wavelength for 118km

Nokia announced two performance metrics for its recently-announced sixth generation super-coherent Photonic Service Engine, PSE-6s: 1.2 Tb/s over metro distances (118km) and 800 Gb/s over long haul distances (2,019 km), both using a single wavelength.

Both field records were achieved on GlobalConnect’s live optical network in Europe. 

The 1.2 Tb/s speed was using Nokia’s PSE-6s optics deployed over a wavelength division multiplexing (WDM) network using 150 GHz of spectrum on GlobalConnect’s Metro Data Center Interconnect links. Data center interconnection was also demonstrated at 800 Gb/s on a single wavelength over 2,000km, paving the way to single-wavelength 800GE transport across long-haul distances with no regeneration. Reducing the number of coherent interfaces needed enables up to 50% network total cost of ownership savings and up to a 60% reduction in network power consumption.

James Watt, President Nokia Optical Networks, said: “With world data volumes expected to double by 2025, there has never been so much focus on cost and power consumption per bit. That is why we launched the PSE-6s and why we are celebrating this first field trial with GlobalConnect, ushering in new era of single-wavelength 800GE client transport to increase network capacity.”

Martin Højriis Kristensen, Head of Market & Operations at GlobalConnect, said: “This trial highlights GlobalConnect’s commitment to offering scalable and flexible high-bandwidth services across our Nordic backbone network. We are pleased to validate Nokia’s latest generation of PSE-6 super coherent optics as an important enabler of these continuous network upgrades, seamlessly operating over our live network with existing coherent channels.”
