Terralpha and Nokia recently set a new record in France by achieving a data rate of 800 Gb/s over a distance of more than 800 km between Bordeaux and Marseille. This record was achieved by activating an 800 Gb/s wavelength on the network Terralpha's production facility, marking a major step forward in the field of optical communications. Terralpha's network already offers speeds of 400 Gb/s per wavelength, and this latest achievement demonstrates that it will soon be able to support services of 800 Gb/s and more, meeting the needs of the next generation of technologies.
This record was achieved between two strategic data centres connected to several undersea cables: in Bordeaux with Amitié, and in Marseille with 2Africa, Medusa, Atlas Offshore, SeaMeWe-6, and many others. This technological advance strengthens Terralpha's position as a key operator for connecting the Bordeaux and Marseille hubs. It also offers a glimpse of the future capabilities of its network across the whole of mainland France.
Nokiain partnership with Terralpha, has achieved a new technological feat with its PSE-6s transmission optics, enabling speeds of 1.2 Tb/s per wavelength, ideal for interconnecting data centres. On Terralpha's network, a wavelength of 150 GHz was used to pass through 4 data centres, 7 ROADM optical cross-connect sites and 7 amplification sites, achieving a record throughput of 800 Gb/s, pushing back the current limits of data transport in France.
This technological breakthrough enables data to be transported at 800 Gb/s over a single wavelength, offering greater capacity and efficiency to meet the needs of businesses and public services. Customers benefit from faster, more reliable and secure communications, with reduced latency and improved quality of service. As well as reducing energy consumption and optimising resources, this technology contributes to social responsibility by promoting a more stable connection, reducing the digital divide and stimulating innovation.
