Nokia and GlobalConnect have conducted the first network trial of the sixth-generation super coherent photonic service engine PSE-6s, achieving a breakthrough in single-wavelength 1.2Tb/s transmission performance and setting a new industry record, according to official news from Nokia Bell.
Nokia recently announced that it and GlobalConnect have broken two optical transmission records in European network trials. The trial used Nokia’s sixth-generation Super Coherent Photonic Services Engine, PSE-6s, to achieve 1.2Tb/s metro (118 km) and 800Gb/s long-haul (2019 km) transmission using a single carrier.
The 1.2Tb/s transmission rate achieved in the WDM live network trial was achieved when Nokia deployed PSE-6s on GlobalConnect’s metro data centre interconnect link and used 150GHz of the spectrum. Similarly, single-wavelength 800Gb/s rates are achieved over 2000 km of data centre interconnect distance without regeneration, setting the stage for long-haul single-wavelength 800GE transmission. In addition, by reducing the number of required coherent interfaces, it can save up to 50% of the total cost of ownership of the network and reduce network power consumption by up to 60%.
With the world’s data volumes expected to double by 2025, there has never been a greater focus on cost per bit and energy consumption,” said James Watt, president of Nokia Optical Networks. That’s why we’re launching PSE-6s, and why we’re conducting our first live network trials with GlobalConnect as we usher in a new era of single-wavelength 800GE client transport to increase network capacity.”
The Nokia PSE-6s has made its debut at Mobile World Congress in Barcelona (MWC 2023, and will be at the Optical Fiber Communications Conference (OFC) in San Diego.
PSE-6 can also operate on existing WDM networks designed around n x 50 GHz wave paths. This enables network operators to achieve efficient operational upgrades and help transform their networks to higher performance and more sustainable energy efficiency.
